Distance, diameter, and the GPM / volume, all affect friction loss. As water passes through the hose / pipe, friction between the water and the inside surface of the hose / pipe causes turbulence. This turbulence reduces the energy produced by the pump (PSI). As a result, the PSI at the other end of the hose will be lower. The higher the GPM passing through a hose or pipe, the more turbulance

### Friction Loss Calculator

Hose length, diameter, and GPM (volume) all affect friction loss. As water passes through a hose, friction between the water and the inside surface of the hose causes turbulence, which slows the water. The results in a PSI drop (pressure loss) at the other end of the hose. The higher the gpm passing through a hose, the more turbulance and friction loss will result.
