Fluid Flow Table of Contents
Hydraulic and Pneumatic Knowledge

Use this equation to determine the torque created by a hydraulic motor with respect to the motors displacement.

T = (PSI  x D)/ (24 x 3.14157)

Where:

T is torque in foot - lbs
D is displacement in cubic inches per revolution
PSI is pressure difference across motor
