Fire Hose Friction Loss Cheat Sheet
Fire Hose Friction Loss Cheat Sheet. 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.
Divide by 2.3 (2.3 is the amount of lift (in feet) that 1psi. Most of the fog nozzles have. Loss of pressure created by the turbulence of water moving against the interior walls of fire hose or appliances. Add lift and friction loss together 4. App = appliance friction loss. 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. Web np = nozzle pressure. Web determine the lift (in feet) 2. Some figures may be used more than once;
