HYDRAULIC FORMULAS

Torque  •  Horsepower  •  Speed Relations in Hydraulic Pumps & Motor

T = (HP X 5252) / RPM HP = (T x RPM) / 5252 RPM = (HP X 5252) / T

Definitions:  T = Torque, foot - lbs.

Hydraulic Power Flowing Through the Pipes

HP = (PSI X GPM) / 1714

Definitions:  HP = Horsepower •  PSI = Gauge pressure, lbs/sq. inch  •  GPM = Flow, gallons per minute

Force Developed by an Air or Hydraulic Cylinder

F = A x PSI

Definitions:  F = Force or thrust, lbs.  •  A = Piston area, square inches  •  PSI = Gauge pressure, lbs/sq. inch

Inch & Millimeters (MM) Conversions

MM = inches x 25.4  •  Inches = MM x 0.03937
