Cylinder Speed Calculator
for Extension

Calculate the extension speed of a cylinder with this
Cylinder Speed Calculator.

Piston Radius (inches):
Flow Rate(Gallons/Minute):
To determine extension speed of a cylinder, input the piston radius
and the flow rate.

How do you find the extension speed of a cylinder?

To find the extension speed of a cylinder, use this
cylinder speed formula:

Cylinder Rod Extension Speed (Inches/Minute) = ( 231 x Q ) / Ap

Q = Flow Rate in Gallons per Minute

Ap= Piston Area = Pi x r2 = 3.1416 x r2

A cylinder with a piston radius of 3 inches and flow rate of 10
Gallon/Minute has a rod extension speed of:

Extension Speed = ( 231 x 10 ) / ( 3.1416 x 32)

Extension Speed = 81.6993 inches/minute or 1.3617 inches/second
(rounded to the nearest 10,000th)
