Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Chezy's equation is used to calculate velocity of flow in open channels.
Step 1: Chezy's equation is: \[ V=C\sqrt{RS} \]
Step 2: Here, \(V\) is velocity of flow.
Step 3: \(C\) is Chezy's constant.
Step 4: \(S\) is the slope of the energy line or bed slope.
Step 5: \(R\) represents hydraulic radius. \[ R=\frac{\text{Area of flow}}{\text{Wetted perimeter}} \]
Step 6: Therefore, in Chezy's equation, \(R\) stands for hydraulic radius. \[ \boxed{\text{Hydraulic radius}} \]
