5 Inch Friction Loss Chart
This friction loss table was designed to be printed on standard 8.5 x 11 paper. Start by right clicking on the image and select the "Save image as" option. For best results we recommend you set the printer to fill the page & adjust/reduce the margins to minimize wasted space. If you're using windows 10 select "Full page photo" in the print pictures window.

100 ft of 5 inch hose with 1000 gpm
Friction Loss Explained
Friction loss occurs when water passes through a hose. 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 at the other end of the hose. The higher the gpm passing through a hose, the more turbulance and friction loss will result.
