Friction Loss Table For Fire Hose
Fire Hose Friction Loss Cheat Sheet. All three factors must be considered. Some figures may be used more than once;
Web friction loss is determined by the gpm flowing, the size of the hose and the length of the hose. Divide by 2.3 (2.3 is the amount of lift (in feet) that 1psi. Web np = nozzle pressure. Some figures may be used more than once; Most of the fog nozzles have. Web determine the lift (in feet) 2. App = appliance friction loss. Loss of pressure created by the turbulence of water moving against the interior walls of fire hose or appliances. Elev = elevation loss or gain. All three factors must be considered.
Add lift and friction loss together 4. Web friction loss is determined by the gpm flowing, the size of the hose and the length of the hose. Add lift and friction loss together 4. Some figures may be used more than once; Elev = elevation loss or gain. Web np = nozzle pressure. Divide by 2.3 (2.3 is the amount of lift (in feet) that 1psi. App = appliance friction loss. Determine the friction loss in the intake hose used 3. All three factors must be considered. Most of the fog nozzles have.
