In the equation Q = Cd × A × √2g × H^3/2, what does 'A' represent?
6. In the equation Q = Cd × A × √2g × H^3/2, what does 'A' represent?
- Acceleration due to gravity
- Coefficient of discharge
- Cross-sectional area of flow
- Head of water above the weir crest
Answer: C) Cross-sectional area of flow
Explanation:
'A' represents the cross-sectional area of flow over the weir. It is one of the factors that determine the flow rate through the weir.
