Useful Formulas

Pump Output Horsepower: HP = GPM x PSI ÷ 1714

Pump Input Horsepower: HP = GPM x PSI ÷ 1714 ÷ E

Pump Input Torque (Lbs. ft.): T = CID x PSI ÷ 75.36

Gallons Per Minute: GPM = CID x RPM ÷ 231

Cubic Inches Displacement: CID = GPM x 231 ÷ RPM

Horse Power: HP = T x RPM ÷ 5252

Flow in GPM using P.T.O.: GPM = Engine RPM x P.T.O.% x CIR ÷ 231 x E

CCM Conversion: CCM = CID x 16.39

CID Conversion: CID = CCM x .06102
