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. Friction loss examples: 100 ft 1" @ 100 gpm = 150 PSI 100 ft 1 1/2" @ 100 gpm = 24 PSI 100 ft 1 3/4" @ 150 gpm = 34.88 PSI 200 ft 1 3/4" @ 150 gpm = 69.75 PSI 100 ft 1 3/4" @ 185
