For a prismatic irrigation canal of wetted area A, having a bed slope S and hydraulic radius R, the chezy’s formula for computing the average velocity of flow through the canal v is given as : (Take C as Chezy’s co-efficient)
1
\(v=C{\sqrt{R\over S}}\)
2
\(v={1\over C}{\sqrt{R\ S}}\)
3
\(v=C{\sqrt{S\over R}}\)
4
\(v=C{\sqrt{R\ S}}\)
