Chezy Formula

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	\(\large{ft}\)	\(\large{m}\)
