`V = L * pi * ( D "/"2)^2`

Enter a value for all fields

The **Pump Cylinder Volume **calculator computes the displacement volume (V) of one stroke of a pump cylinder based on the stroke length (L) and cylinder diameter (D).

**INSTRUCTIONS**: Choose units and enter the following:

- (
**L**) Stroke Length of Pump Cylinder - (
**D**) Diameter of Pump Cylinder

**Pump Cylinder Volume (V): ** The calculator returns the displacement volume in gallons. However this can be automatically converted to compatible units via the pull-down menu.

The formula for the displacement volume of a cylinder in a pump is:

V = π•(D/2)²•L

where:

- V is the volume displaced in one stroke of the pump
- D is the inner diameter of the pump cylinder
- L is the pump cylinder stroke length
