Pipe Volume Calculator

The Pipe Volume Calculator calculates the volume of a round pipe segment based on pipe size and length. The total volume in the entire piping system can be obtained by adding up volumes of individual segment of pipes of different sizes.


The estimation of volume of a piping system can be useful for sizing of different applications. For example, the rule of thumb estimation of the volume of expansion tank of a chilled water system can be taken as 1% of the total volume of a chilled water piping system.


A downloadable version of Excel File is available below for the computation of the total pipe volume in a system.
