Pipe Diameter Calculator

Water consumption in the pipe, l/s
The speed of water in the pipe, m/s
Inside diameter of pipe, mm


With this online calculator you can calculate of the water pipe diameter by flow rate.

Formula:

d = √ (4000q / πv)

d - inside diameter of pipe
q - water consumption in the pipe
v - speed of water in the pipe

A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow.
