Chezy Formula

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Chezy formula, abbreviated as Ch, applies to the steady velocity with turbulent flow in a open channel.

 

Chezy formula

\(\large{ v =  C \; \sqrt{  r_h \; m }   }\) 
Symbol English Metric
\(\large{ v }\) = flow velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ C }\) = Chezy coefficient \(\large{dimensionless}\)
\(\large{ r_h }\) = hydraulic radius \(\large{\frac{rotation}{sec}}\) \(\large{\frac{rotation}{s}}\)
\(\large{ m }\) = slope \(\large{ft}\) \(\large{m}\)
