Friction Loss Table For Fire Hose
Fire Hose Friction Loss Cheat Sheet. Web np = nozzle pressure. Elev = elevation loss or gain.
Web friction loss is determined by the gpm flowing, the size of the hose and the length of the hose. App = appliance friction loss. Most of the fog nozzles have. Some figures may be used more than once; Divide by 2.3 (2.3 is the amount of lift (in feet) that 1psi. Add lift and friction loss together 4. Elev = elevation loss or gain. Loss of pressure created by the turbulence of water moving against the interior walls of fire hose or appliances. Web np = nozzle pressure. Determine the friction loss in the intake hose used 3.

Some figures may be used more than once; Elev = elevation loss or gain. Determine the friction loss in the intake hose used 3. Web friction loss is determined by the gpm flowing, the size of the hose and the length of the hose. All three factors must be considered. Loss of pressure created by the turbulence of water moving against the interior walls of fire hose or appliances.
