Question

In an ogee – shaped spillway, the discharge is proportional to:

1. H^1.5
2. H^0.5
3. H
4. H^2.5

Answer 1

Correct Answer - Option 1 : H^1.5

Explanation:

The Discharge over an Ogee Spillway is given by 

\(Q = C \times {L_e} \times H_e^{\frac{3}{2}}\)

Where,

C is the Coefficient of discharge

L_e is the length of the spillway crest

H_e is the Total head above the crest
