WebJan 23, 2024 · The friction loss formula allows you to calculate the friction loss you experience from the pump to the nozzle. This number affects the pump discharge pressure needed to achieve your desired flow rate. FL = friction loss coefficient X (flow rate / 100)2 X (hose length / 100) OR. FL = C (Q/100)2 X (L/100). FL: Friction Loss in PSI. WebNFPA
