That said we put together the following tables to serve as general guides for estimating a pipe s water flow capacity.
1 1 2 pipe capacity.
For a pipe use its length instead of height.
Pipe volume π radius length where radius inner diameter 2.
The formula for the volume of cylinder is.
The volume of a pipe is equal to the volume of a liquid inside if a pipe is fully filled with it.
Cylinder volume π radius height.
Volume π d 2 4 h thus the volume of a pipe is equal to pi times the pipe diameter d squared over 4 times the length of the pipe h.
Water flow gpm gph based on pipe size and inside outside diameters.
