Wells & water/ CALCULATOR

Water volume inside a pipe

Calculate how many litres a straight pipe run holds from its internal diameter and length.

Use the actual bore, not the nominal pipe size or outside diameter.
Add the measured lengths of the sections that will contain water.
Contained water

14.7 L

Water per metre

0.491 L/m

A fully filled circular pipe with constant internal diameter. Fittings, tanks, branches, trapped air and pipe-wall tolerances are excluded. Check manufacturer dimensions for multilayer and nominal-size pipe.
