Flows up to 10 gpm: 20" Big Blue Cartridge Fitler Systems. Each double-jacket fire hose is manufactured-to-order and stamped with the manufacturing date. COMPONENT; SPECIFICATION; INSPECTION; MAINTENANCE; DIAGNOSIS; SI UNITS . Then the length of the hose directly. Hoses. LDH Hose is big-flow, low-pressure hose, which is both its defining feature and. So too should fire departments investigate and implement better, more effective tactics and methods of combating more intense fires. Keep in mind, water pressure in homes can range from 40 PSI to 80 PSI. He is a nationally recognized instructor on large-flow water delivery. It will deliver the same flow as 1 3/4-inch line at about half the engine pressure, or almost double the volume at the same engine pressure. All three hoses we compared use a standard 1 1/2 National Standard Thread (NST) couplinga frequently-used hose coupling in the fire serviceand operate at up to 400 PSI. When you know how much water you want to be applied, you can calculate the exact amount of time to leave your hose on. Because of its ability to provide easily attainable flow rates up to about 250 gpm, many of these officers are evaluating two-inch hoselines coupled to low-pressure or smooth-bore nozzles as an effective alternative to 1 3/4-inch and 2 1/2-inch hoselines when staffing is limited. This will keep you from wasting water or applying not enough water. Always check your hose before using and fix any leaks. DC Firefighters Rescue Seniors from 8-Story Building, NVFC, VCOS, ISFSI Release Operational Training Guide, LEGO Masters Firefighting Team 'Built' on Friendship. You can then decide if you need a hose with a high flow rate that will quickly deliver a lot of water but will likely be heavier or a hose with a low flow rate that will deliver water more slowly but be lighter. We did not get anywhere close to 360 psi on any of the lines we tested. With over 1.6M products and 24/7 customer service we have supplies and solutions for every industry. By following proper procedure for cleaning, use, storage, testing, and inspection, Superiors fire hose can last 10 years or longer.

Rebel Attack Hose Angus Rebel attack hose, is a first responder firefighting hose that can withstand flames . The flows for the two-inch start at 185 gpm because this line can be used for both low- and high-flow operations-185, 210, 265, 325, and 400 gpm. Fire hose sizesin this case, 1 1/2 inch, 1 3/4-inch, and 2 inchrefers only to the dimensions of the inner rubber hose liner. A. 1 Has Darley Build WASP Quick Photo Apparatus of the Day: November 15, 2022, One Dead, Others Injured After Crash Involving Fire Truck in OR, Prince George Firefighters Buckle Up for Safety, The flow tests comparing two-inch and 2-inch hoselines used, The two-inch hose was able to match the 2-inch hose in every, Because the two-inch hose is smaller than the 2-inch line, it. Pressure and Return (any pressure or return hoses) should not exceed 15 feet per second. The fire is small and does not appear to be spreading. This chart is designed (using the friction loss formula) to find quick and accurate answers for 1 1/2" fire hose friciton loss.To find the friction loss for a 100 foot section of fire hose, find the column with the desired GPM and to its right you'll see the corrosponding friction loss. We tested the standard two-inch with 1-inch couplings weighing 20 pounds per 50-foot section as well as two-inch hose with 2-inch couplings, which is a new concept. . Looking for Fire Hose Nozzle, 1-1/2 In., Brass? This hose flows roughly 150 gallons per minute. multiply GPM x .13380 KEY FIRE HOSE CORPORATION WATER FLOW LOSS (PSI PER 100 FEET . 2-inch double-jacket fire hose weighs in at 40 pounds dry and flows up to 250 gallons per minute, making it 30 percent heavier (but 100 GPM faster) than the lightest hose. If it is decided to utilize a 100-psi combination nozzle on the business end, it makes more sense to utilize 2 1/2-inch hose because that line's increased weight can help the nozzle operators to better cope with relatively high nozzle reaction forces. Probably the most practical method of utilizing two-inch hose without having to inventory a number of adapters is to equip it with couplings having common 1 1/2-inch hose threads. Zoro # G2003251 Mfr # 6AKC7. Hose Ends and Fluid Conveyed In most cases, the end fitting openings are slightly smaller than the hose itself. To find the friction loss for a 100 foot section of fire hose, find the column with the desired GPM and to its right you'll see the corrosponding friction loss. Copyright 1998-2012, Firehouse.com, A property of Southcomm Inc. All times are GMT-5. Mulch & Bark Blowing Hose. 3. In photo 2, we see one such device. Use the charts below to compare flow and reach data for Akron Brass nozzles, including smooth bore nozzles, straight stream, combination nozzles, and more. This had the effect of materially reducing the per-foot cost of two-inch line to little more than 1 3/4-inch hose. Just when fire departments are realizing the need to flow more water on more intense fires, however, many are being forced to operate with fewer members. 2. As we do with all our contributors, we ask him to use his hands-on experience with these hoses to provide authentic advice to our audience. One thing to add about the flow tests is that the nozzle reaction for flows above 250 gpm with the two-inch hose was severe enough to cause the hose to buckle right at the nozzle. Firefighters regularly drag, bend, and carry attack hose. The reason for the 2-inch couplings is to reduce the friction loss. It is somewhat heavier than 1 3/4-inch hose when filled with water, approximately 65 pounds per 50-foot length vs. 54 pounds for 1 3/4-inch line, but not nearly as heavy as 2 1/2-inch hose, which weighs approximately 120 pounds. To find the maximum flow you would need to know the maximum pressure. Putting that into another perspective, if it took 13,000 gallons of water to put out a fire or clean a pier, you could do your job 14 minutes faster with a 1 3/4-inch hose. as the hose, down to as much as 1/8" Solid stream nozzle on hand lines 50 psi nozzle pressure Solid stream on master streams 80 psi Solid stream nozzle flow calculation GPM = 29.7 x d2 x NP (square root of) / GPM= gallons per minute, 29.7 is a constant, d = diameter of the orifice in inches, NP = nozzle pressure in PSI Mechanical principles of fog streams Firefighters cautiously refer to 1 3/4-inch double-jacket fire hose as all-purpose hose. If you are wanting a higher flow rate, it is always best to use the shortest hose possible. Just follow the package directions on how to use the gauge. While firefighters might feel a sense of relief in trading their 2 1/2-inch big-water handlines for 2-inch fire hose, commercial and industrial users may find them too unwieldy. 2-inch double-jacket fire hose weighs in at 40 pounds dry and flows up to 250 gallons per minute, making it 30 percent heavier (but 100 GPM faster) than the lightest hose. A second line, in blue, indicates the pump pressure needed to flow 240 gpm on the same line. The reason for going to two-inch hose is to make hose deployment easier-especially for one firefighter. Should the higher PDP be a big concern? Referring to charts 1 and 2, the two-inch hose matched 2-inch hose in every flow category. Actual gallons per minute vary with the nozzle used, available water pressure, and other factors. Find it at Grainger.com. For years, the only practical hoseline size that could flow over 200 gpm was 2 1/2 inches. The stopping point was 220 psi. The tradeoff is two more pounds for the larger couplings (22 pounds total). A review of the reaction forces of various nozzles that can be effectively paired with two-inch attack lines, shows why. 2" diameter hoses are used when higher water flow and low friction loss is desired. Because of these negative traits, firefighters will tend to not choose the 2-inch line. Inventory is low and can be depleted in hours. Assault Nozzles Rated at 100 Psi. A leak in your garden hose is a common reason of a decreased flow rate. Referring to charts 1 and 2, the two-inch hose matched 2-inch hose in every flow category. 17-32 of 339 results for "2 inch fire hose" RESULTS 2" x 50ft PVC Lay Flat Discharge Hose With Aluminum Camlock C & E Fittings, Cam Lock Fitting Type A included, Heavy Duty Reinforced Pump Backwash Hose Assembly 53 $5799 FREE delivery Mon, Nov 14 2" x 50' Coupled Aluminum Shank IPT/NPSH Single Jacket Mill Hose (250 LB Test) 5 $10164 15 psi - 610 gpm. Here is the hydraulic hose flow rate formula, helping you calculate the result of hose flow rate. Call us at +1 (888) 361-6662 or email [emailprotected]. For example, the Memphis Fire Department marks its gauges in two increments. 2. . This insures that the interior crew can easily maneuver and safely operate the line yet still flow enough water to handle about three to four rooms of fire. Suction lines (hose between the reservoir and pump) should not exceed 4 feet per second. 1-1/2 Rack Fire Hose (500 LB Test) $ 72.00 - $ 180.00 Select options; 2-1/2 Rubber Covered Fire . In this episode Jeff Shupe reviews the historical evolution of 2" hose and its fit in today's fire service as an intermediate size hose line, balancing high flows with mobility utilizing a. 2" 2 1/4" 2 1/2" 3" SMOOTH BORE DISCHARGE DATA POCKET FLOW GUIDE (GPM) 72 74 76 78 80 82 84 86 88 90 92 94 96 98 100 105 110 115 120 125 130 135 140 145 150 175 200 P.O. To do this, you will need a bucket or container and you will need to know how many gallons of water it holds. We have also relied on him to use and test other hose accessories, like storage reels and spray nozzles. Water Flow Rate. (2) Flows may vary with brand or condition of hose. Water Hose Flow Rates Air Line Sizing PSI at Hose Nominal Hose Diameters Inlet 1/2 5/8 3/4 1 11/4 11/2 2 21/2 3 4 6 8 . Pull hose entirely off rack (or else water will not flow). We ask our contributors to perform hands-on testing of garden hoses so that we can pass on useful information to our customers. If more water is needed, the supervisor can radio the pump operator to provide more pressure that will allow the interior crew to flow more water without having to stop the attack to change nozzle tips. Flow Capacities of Hose Assemblies. Using this information, we can determine the flow rate (Q) as follows: Q = Area * Velocity Q = (0.349 ft 2) * (16 ft/s) Q = 5.584 ft 3 /s Sensing a need in the market, one coupling company developed an expansion ring drawbar that allowed the installation of inexpensive three-piece couplings on two-inch hose. AkroFlow Portable Flow Meter Use AkroFlow for precision flow management, so you can know your flow on the fireground. This is where the two-inch line comes into play. e.g., hose length. The 2-inch hose did not have a problem with nozzle reaction at all. Two-Inch Hose: the Lightweight Preconnected Little Big Line, RIBCRAFT Fulfills Contract With the California Department of Fish and Wildlife, NY DEC: Nearly $640K in Volunteer Fire Assistance Grant Funding Now Available, FOL-DA-TANK Acquires EVAC Systems Fire and Rescue, Chris Higgins Named Telgian Fire Safety President, Brooklyn FDNY Apparatus, Station Shot Up in Street Gunfight. Two-inch hose is a relatively common size in the marine industry and has been available for years. The Hydrant Flow Test Calculator measures the rated capacity at 20 psi of a fire hydrant. He is also a retired engineer from the Las Vegas (NV) Fire Department. It is not much larger in flat width than 1 3/4-inch hose. NOTE:To find cubic ft/min. Keeping that in mind, we decided to use a short piece of 2-inch five feet long at the end of the two-inch handline for the sole purpose of absorbing nozzle reaction to assist the firefighter with handling the high flows. While single jacket fire hose weighs less and bends more readily, double-jacket fire hose better resists pressure, abrasion, and tearing. Often, the same amount of two-inch hose will fit in the hose bed space as the smaller line. The pump pressure is set to supply 38 psi at the tip, which generates 230 gpm at 72 pounds/force reaction. Approximate pressure loss expressed in pounds per square inch (psi) per 100 foot length of straight, smooth bore hose. There was a 40-psi reduction in the PDP flowing 325 and 400 gpm by using the 2-inch couplings. If more punch is needed, the officer can call for 15 pounds more pressure, which provides an offensive flow rate at 250 gpm. PAUL SHAPIRO is director of Fire Flow Technology. Model # 6AKC5 UNSPSC # 46191603 Catalog Page # 1819 1819 Proper nozzle selection becomes extremely important if it is desired to exploit the two-inch line's full potential. Those pumps, in turn, deliver water to attack hose. Knowing the flow rate ahead of time, will help you decide on which hose you may want to buy. Pressure and gallonage provide different benefits to firefighting and pressure washing applications. Because the two-inch hose is smaller than the 2-inch line, it does not handle the nozzle reaction as well. The flows for the 2-inch started at 265 gpm because it is considered a high-flow handline. With access to thousands of products available online, eDarley is an expansion of our print catalog.We are continually improving the shopping experience by providing the largest selection of fire equipment from industry leading brands including Akron Brass, Key Fire Hose, Fire-Dex, Bullard . The nozzles used for this test are smooth bore tips for a 50-psi nozzle pressure. As a matter of fact there is an extremely easy way to move the water: Just sit on it! Founded in 1908, Darley is a leading provider of firefighting equipment, rescue gear, tools and supplies. During an attack operation, if the officer feels that more flow is needed, he or she will radio the pump operator to increase the pressure to "blue-two." The actual connection will not affect flow rate. Different manufactures produce master stream devices that are fed by a single 2-inch hose. It is always a good idea to measure or walk off the distance between your spigot and where you will use the hose before buying a new hose. The high end of the large-flow handline is normally 325 gpm. This has led many departments to believe manufacturers' claims that the 1 3/4-inch line could flow up to 300 gpm on the fireground; however, the high engine pressures (above 300 psi) needed to generate this flow rate makes the line extremely stiff and hard to handle. Simply put, if you don't flow enough water, the fire will not go out and the interior operating crew will remain in increasing danger until withdrawn. Key ECO-10 fire hose claims 7.5psi friction loss in their 2-inch hose at 185gpm in 50 foot lengths. This is usually done by the first-in unit. It has the same 1 1/2-inch thread size couplings as other attack lines and is as easily deployed by as few personnel. When theres a need for pressure or volume, fire hose delivers. How does it handle? QRFS offers 1 1/2 inch, 1 3/4-inch, and 2-inch double jacket fire hose in 50, 75, or 100-foot lengths. Visit our water hose kink guide if you want to learn more tips on how to prevent them. Available . In the majority of the cases, I would say yes. As bigger fires naturally require more water to eliminate, firefighters should be accustomed to easing all hose sizes. But first, well provide some background on fire hose and explain some need-to-know terms manufacturers use to describe double-jacket fire hose. To lower the nozzle reaction force, it may be wise to investigate the advantages of low-pressure combination or smooth-bore nozzles. More waterthat is, more GPMcan absorb more heat, reducing the temperatures of burning materials and the surrounding air. Flow of water in Hose Inside Diameter: In each block of instruction, we reviewed department standard operating procedures (SOPs) and then flowed the three sizes of attack handlines (134, two, and 212 inch) found on engines. Water will flow when hose is entirely off rack and nozzle is open. The GPM would be between 300 GPM . Because the two-inch will have a higher friction loss at the high flows we tried to achieve, a nozzle with a low nozzle pressure kept the overall discharge pressure as low as possible. Use these fire hoses and accessories for industrial, residential, or commercial firefighting or other projects requiring heavy duty hoses. According to that National Fire Protection Association (NFPA), this means the hose can be used at up to 360 psi on the fireground. Angus Fire manufactures a range of covered fire hoses including the world's leading BS6391 Kitemarked fire hose Duraline. He has specifically contributed to the testing of hose flow rate, crush-resistance, and weight. The actual flow will probably be less. While 150 GPM may be plenty in many situations, this hose . For example, after extensive. 3. 45M 45M 45M60M 60M 60M75M 75M 75M 3.5 15.5 14 12 10 8.6 7 5.2 38mm HOSE 45mm . If you do not know these 3 measurements listed above, there is an another way to determine your hose flow rate. Firefighters frequently distinguish between attack hose and supply hose. While flow rate will vary based on hose length, hose diameter, and source water pressure, the most common flow rate will be between 10 and 25 gallons per minute. While there have been hundreds of thousands of discussions throughout the fire service on, for example, the flow merits of one nozzle or the penetration qualities of another, it must be understood that the most important element of attack line operation is gallons per minute (gpm). You can always buy an additional hose and connect to it later if you end up needing a longer hose. Ground Fish, Rotary Drilling, and Rock Dust Hose (Misc) Interlocked Metal Hose. But well also consider how they perform in commercial and industrial applications. In firefighting, water moved at high pressures can better penetrate burning materials. Water Flow Time. So, which hose delivers the most volume per pound of dry weight? Most garden hose diameters are one of three sizes listed below. Hoses designed for suction have fabric or wire designed to stop the hose from collapsing. Note the difference in PDP with the two types of two-inch equipped with 1-inch and 2-inch couplings. When you connect two hoses together, the flow rate will only decrease due to the added length. A fire hoses rated GPM provides an upper limitnot the exact pressure. The rated capacity calculation is useful in determining the total water supply at a given point in the hydrant or water main. Dragging a hose around the yard or worksite can be cumbersome and at times strenuous. The main reason for having a large-flow preconnect is to make a quick large-flow attack on a significant fire to achieve a quick knockdown. I've googled and looked everywhere without success for a chart, or listing of flow capacities for fire hose for these sizes 1 3/4", 2 1/2", 3", and 5". Nozzle Flow/Reach Data. Just because it has worked in the past doesnt mean it cant be done better. It all depends upon how much pressure you are able to supply in getting the water through the hose line. Open nozzle. Print this . Whether the staffing on your engine company is four firefighters, three firefighters, or even two firefighters, when a first-in engine company is faced with enough fire to warrant the initial line being a 2-inch, lets face it-you dont have enough people. The 1 1/2-inch double jacket fire hose provides 5.06 gallons per minute per dry pound of hose (150 GPM / 29.6 lbs dry = 5.06 GPM/pound). There is no single flow volume for fire hose. If your mind is already made up, click here to browse our selection of 1 1/2 inch, 1 3/4-inch, and 2-inch double-jacket fire hose. All rights reserved. The fire is not between you and the exit. The extra layer of reinforcement provided with a double-jacket fire hose makes it ideal for use as an attack hose. This chart is designed (using the friction loss formula) to find quick and accurate answers for 2 1/2" fire hose friciton loss. Since the pressure will not be increased until called for, the officer has time to prepare the crew to handle the increase in nozzle reaction, which is approximately equal to that of a 100-psi nozzle flowing the same amount of water on a 2 1/2-inch line. This page was generated at 08:51 PM. Looking for Fire Hose Nozzle, 1-1/2" Inlet Size, NST? Consider the fact that to continue to send firefighters inside a structure to combat fires of ever-increasing intensity, with lines that flow a marginal amount of water, is simply increasing the possibility of firefighter injury and death, without having any appreciable positive outcome on limiting fire damage. This system has proven to be extremely flexible and, with a little training, extremely effective since it allows a single, easily stretched handline to be operated at relatively low pressures for the majority of fires but, has enough cushion built in that enables a first-in crew to flow 21/2-inch-size streams when necessary. The stream reaches about 70 feet and, despite the high flow, can be handled quite easily by a trained operator. While standard pressure combination nozzles can function well from a flow standpoint, the combination of a high flow rate exiting the nozzle at 100 psi generates nozzle reaction forces that could cause handling problems when they are operated by one or two firefighters. Combatting fires in occupancies of the 1990s requires more water to combat more intense fires. If anyone could help with providing these figures (in terms of GPM's) or give a link to a source that could help, it would be greatly appreciated. Need help choosing the right double-jacket fire hose? When using a hose, knowing how much water is coming out is very important. But 2 1/2-inch line, while it can be easily stretched before it is charged, becomes almost impossible to operate offensively (moved rapidly) inside a building by a crew with limited staffing. Take a look at the 2-inch nozzles in use today. It's been noted that two-inch hose can usually be packed in the same beds as the present attack lines, can be easily moved into a fire building when charged and has the potential of supplying in-creased flow rates. In a search for an answer, it's been described how 1 3/4-inch line could be designed to address the problem of the high-flow handline. If you have 5/8 diameter hoses connected to a source with 40 PSI, here are the flow rates for the three most common lengths. When it comes to large-flow handlines, the 2-inch hose has always been the weapon of choice, because its lower friction loss capabilities allow for more flow. You can also find hose timers that will shut the hose off for you after a certain amount of time. While 150 GPM may be plenty in many situations, this hose trades ease of use for lower flow rates. Not long ago, police officials realized that the .38-caliber revolver was not effective as it used to be, given the increased intensity of criminal activity and firepower. SKU: 3775. Common sense tells us that fire service planners need to address the problem of increasing the gpm flow rate per line to better cope with larger fires but must also keep in mind that for that flow rate to be effective, the line has to be capable of being maneuvered inside a fire building by as few as two firefighters. The drawback to using 2-inch line is that it is heavy, making it tough to deploy, especially in a quick-attack mode. And pressure-washing companies like Denver Pressure Washing Services prefer fire hose when cleaning large or very dirty parking garages. Water pressure rates do vary by home though, and can get as high as 80 PSI. The pressure is sometimes stated as 'head of water'. No twist to the left is permitted. Fire Hose - 3" x 50' -w-2 Couplings-FREE SHIPPING-Off White. Many firefighters prefer 1 1/2-inch double jacket fire hose as their attack line. (3) Flows are approximate and do not reflect losses in preconnect piping. Striving to do a better job means being able to constantly review and change things as needed. Standard practice on ships has been to equip the hose with two-inch threaded couplings; in some areas of New England, the use of two-inch hose equipped with one-third-turn Storz couplings is relatively common. Use this when fire flow testing hydrants. This article focuses on the large-flow preconnected handline with a different twist to it: using two-inch hose for the preconnected high-flow handline to make this big-hit line easier to deploy. This shortage becomes critical during first-arriving-company operations, when relatively few on-scene firefighters have to simultaneously perform command, size-up, rescue and fire suppression operational tasks. The higher the water pressure, the higher the flow rate. through a hose depends on the rate of flow , the viscosity of . David P. Fornell goes over the advantages and disadvantages of using two-inch hose. It can be seen by the chart on page 135 that a low-pressure nozzle rated 200 at 75 psi can deliver this flow while generating a relatively easily handled reaction force of only 64 pounds/force reaction. 4. With over 1.6M products and 24/7 customer service we have supplies and solutions for every industry. If you want to flow more water with a limited staff, a good place to begin is to design a line that provides a relatively easy-to-handle conduit (hose size) coupled to a nozzle that flows a lot of water but doesn't generate unmanageable nozzle reaction force. . Paul Shapiro at Fire Rescue Magazine suggests that a single trained firefighter can handle a hose of this sizealbeit with some effort: Flow rate Q is defined to be the volume of hydraulic fluid passing by through a hydraulic hose during a period of time. Two-inch line offers a number of advantages: Two-inch line also has some disadvantages: Before deciding to add two-inch hose to a firefighting toolbox, departments must understand that it creates the enigma of being able to more easily deliver high flow rates to the nozzle yet creates the problem of whether the nozzle operator can safely and effectively use these flows during attack operations. But for filling our hypothetical swimming pool, this hose comes in handy. Take the square root of 55 psi/57.8 psi, which is 0.9755, and multiply by 850 to get 829.16 gpm. To read more, visit our article comparing rubber vs vinyl garden hoses. If you need more water for your job, you will want a larger diameter hose. Three of the most common measurements associated with fire hose are gallons per minute (GPM), pounds per square inch (PSI), and friction loss. View Full Product Details. He has authored numerous articles for fire trade magazines. The example below enables you to find the predicted flow rate at 20 psi residual pressure. The hose under hydrostatic pressure testing shall not twist more than 12.5 degrees per foot for the 2 1/2 inch and 3 inch sizes. Firefighters can pick from available hydrants the one with the best flow, using a traffic light scheme for ease of memory. Assuming the hydrant stays at 60-psi and you are using 100 ft of open ended 2" hose (pressure drop across the line of 60 psi) you will max out in the area of 300 - 320 GPM. Hose - Water Discharge - Imperial Units Water discharge through 100 feet hoses - at pressures ranging 10 - 200 psi: Download and print Hose Water Discharge Chart 1 psi = 6.9 kPa = 0.069 bar 1 ft (foot) = 0.3048 m 1 gal (US)/min =6.30888x10-5 m3/s = 0.227 m3/h Hose - Water Discharge - Metric Units Fire Hose 1-1/2 inch x 100 feet $ 299.00 For Homeowner Swimming Pool Fire Pump 1-1/2 inch x 100 feet Mil Spec 2 ply rubber hose Fire Hose Quick Connectors Note: Fire hose is now in SHORT SUPPLY. Showing: 1-6 of 6. The flow rate will vary according to the cross-sectional area of the channel: Area = * (Diameter) 2 / 4 Area = 3.1415926 * (8/12 ft) 2 / 4 Area = 0.349 ft 2 The area of the pipe is 0.349 ft 2. With a 2 inch nozzle, the average water delivery rates are between 200 and 325 gpm. Hose, Tubing, Ducting. Guidelines issued by the National Fire Protection Association (NFPA) require that the material used withstand damage caused by repeated bending and changes in pressure. While available sizes for double jacket attack line hose range from 1 inch to 3 inches, weve chosen to hone in on the three most common diameters: 1 1/2 inch, 1 3/4-inch, and 2-inch fire hose.
