FORMULA

Torque (ft. lbs) = HP x 5252 ÷ RPM

Torque (ft. lbs) = C.I.D. x PSI ÷ 24π

HP = torque (ft. lbs) x RMP ÷ 5252

HP (in fluid):  HP = PSI x GPM ÷ 1714

Vel. oil in pipe:  V = GPM x .3208 ÷ A
Vel in ft/sec; A is inside area, sq. in.

Hydraulic cylinder speed:  S = CIM ÷ A
S in INS/min; A is piston area, sq. ins.
CIM is pump flow, cubic inches/min

RPM = 336xMPH ÷ d(d = wheel dia, ins)
