Engineering ToolBox > Chezy Formula
The Chezy formula can be used to calculate mean flow velocity in conduits and is expressed as
v = c (R S)1/2 (1)
where
v = mean velocity (m/s, ft/s)
c = the Chezy roughness and conduit coefficient
R = hydraulic radius of the conduit (m, ft)
S = slope of the conduit (m/m, ft/ft)
In general the Chezy coefficient - c - is a function of the flow Reynolds Number - Re - and the relative roughness - ε/R - of the channel.
ε is the characteristic height of the roughness elements on the channel boundary.
