The Double Acting Hydraulic Piston Force calculator computes force produced by a double acting hydraulic piston.

INSTRUCTIONS: Choose units and enter the following:

• (d1) Rod Diameter
• (d2) Piston Diameter
• (P1) Pressure in Cylinder (on side of rod)

Double Acting Hydraulic Piston Force (F1): The results are returns in pounds (force).  However, these can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for the force produced by a double acting hydraulic piston on the rod side is:

F1 = π / 4 (d₂² - d₁²) P1        

    where

•     F1 = rod pull force (lb)
•     d1 = rod diameter (inches)
•     d2 = piston diameter (inches)
•     P1 = pressure in the cylinder (rod side) (lff/in2)
