Access hydraulic cylinder calculations and formulas for accurate engineering analysis on Evolution’s engineering toolbox.
Cylinder Blind End Area (in square inches)
Example: What is the area of a 6″ diameter cylinder?
Formula: π x (Cylinder Radius)2 = square inches
Cylinder Rod End Area (in square inches)
Example: What is the rod end area of a 6″ diameter cylinder which has a 3″ diameter rod?
Formula: Blind End Area – Rod Area = square inches
Cylinder Output Force (in pounds)
Example: What is the pull force of a 6″ diameter cylinder with a 3″ diameter rod operating at 2,500 PSI?
Formula: Pressure (in PSI) x Cylinder Rod End Area = Force in pounds
Fluid Pressure in PSI Required to Lift Load (in PSI)
Cylinder Speed (in inches per second)
GPM of Flow Needed for Cylinder Speed
Cylinder Blind End Output (GPM)
Example: How many GPM come out the blind end of a 6″ diameter cylinder with a 3″ diameter rod when there is 15 gallons per minute put in the rod end?
Formula: Blind End Area ÷ Rod End Area x GPM In = GPM Out
