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

Enter a value for all fields

The **Pipe Volume** calculator * Section of Pipe * computes the volume of a pipe (V), based on the interior diameter(d) of circular conduit or pipe and the length (l) of the pipe.

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

- (
**D**) Inner Pipe Diameter. - (
**L**) Pipe Length.

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

The equation for the volume of a pipe is:

V= π⋅(D/2)^{2}⋅L

where:

**V**= interior volume of a section of pipe**D**= inner diameter**L**= length of pipe
