How much friction do you lose in a fire hose?
Using the hand method, for each 100-foot length of 1¾-inch hose flowing 200 gpm, the friction loss is 48 psi: 2 x 4 x 6 = 48 psi. For a 3-inch supply line flowing 300 gpm, the friction loss per 100-foot section would be 9 psi: 3 squared equals 9 psi.How much water is in a 50 foot hose?

Large-diameter hose (LDH) has a remarkable ability to move large volumes of water at a fraction of the friction loss encountered in conventional, smaller-diameter hose. LDH can be thought of as an aboveground water main laid into an apparatus pumping at a fire or simply as a very long soft-suction hose.What is CPAT training?

The user attaches a hose to the fire hydrant, then opens a valve on the hydrant to provide a powerful flow of water, on the order of 350 kPa (50 pounds per square inch gauge (psig)) (this pressure varies according to region and depends on various factors including the size and location of the attached water main).How fast does a fire hose spray?
Each nozzle has an expected, or rated, gallonage at a rated pressure. For example, a nozzle may deliver 60 GPM at 100 PSI, and 50 GPM at 110 PSI.What is the difference between attack and supply hose lines?
Attack hose is designed to be used by trained firefighters to take down fires too dangerous or too large to be extinguished without professional help. In general, supply hoses are larger and can move larger volumes of water, but may not be built to withstand quite as much water pressure or bend as often as attack hose.
