WebFriction loss can be calculated by theoretical or the fire ground method, and we are focusing on the latter. ... Friction loss in fire hoses is unavoidable. 2. Friction loss … WebFriction loss occurs when water passes through a fire hose. Distance, diameter, and the GPM / volume, all affect friction loss. As water passes through a fire hose, friction between the water and the inside surface of the hose cause turbulence. This turbulence reduces the energy produced by the pump (PSI). As a result, the PSI at the other end ...
