Cylinder Speed Calculator
for Extension

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

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

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

Q = Flow Rate in Gallons per Minute

A_p= 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)
