Web3.3 Friction Loss in Fire Hose. Friction loss is the resulting resistance as water (fluid) moves along the inside wall of either a hose, pipe, or hose fittings. Points to remember about friction loss: Friction loss increases as flow (gpm) increases. Total friction loss varies with length -- the greater the length, the higher the friction loss. WebSame hose at 400 gpm = 12.8psi friction loss Flow doubled 2 – So, friction loss is square of the doubling (2 = 4) thus (3.2 x 4 = 12.8) 3. 5For the same gpm friction loss varies inversely as the fifth power (X ). This principle proves the advantage of a larger size hose Ex > a 3in hose has 0.4 (40%) friction loss of that of a 2.5in hose. So ...
