Water velocity in pipe calculator

Flow rate, l/s =
Diameter of pipe, mm =
Water velocity in the pipe, m/s =

With this online calculator you can calculate velocity of water in the pipe.

Formula:

v = 4000q / πd²

d - inside diameter of pipe
q - flow rate
v - velocity 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.
