# Cylinder Extension Speed Calculator

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

## 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 ) / A_{p}

Q = Flow Rate in Gallons per Minute

A_{p}= Piston Area = Pi x r^{2} = 3.1416 x r^{2}

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 3^{2})

Extension Speed = 81.6993 inches/minute or 1.3617 inches/second

(rounded to the nearest
10,000th)
