Chezy Coefficient

on . Posted in Fluid Dynamics

Chezy coefficient, abbreviated as C, a dimensionless number, dependent on surface roughness and the hydraulic mean depth.


Chezy coefficient formula

\(\large{ C = \frac{1}{n} \; r_h^{1/6}   }\)
Symbol English Metric
\(\large{ C }\) = Chezy coefficient \(\large{ dimensionless }\)
\(\large{ r_h }\) = hydraulic radius \(\large{ ft }\) \(\large{ m }\)
\(\large{ n }\) = roughness coefficient \(\large{ dimensionless }\)
