GuideRequired Flow = Cylinder Volume ÷ Stroke Time
Useful when you know how fast a cylinder needs to move and want to estimate required pump flow.
Calculates required flow for extension and retraction using cylinder area and stroke time.
Results
Required Flow To Extend— L/min— GPM
Required Flow To Retract— L/min— GPM
Piston Area— mm²
Annulus Area— mm²
Important NoteActual flow requirement can vary due to cylinder condition, load, leakage, valve restriction, pressure drop and pump efficiency.
