D is the correct option.

Ganesh said:   7 years ago
Here, V=10.8 R^2/3 S^1/3.

Chinmoy said:   7 years ago
You are absolutely right @Mahe.

All other answer is based on Manning's formula.

Musab said:   7 years ago
The correct answer is R^3/4 S^1/2.
R^2/3 S^1/2 is Mannings equation.
And other equation by Lacey is 16 R^2/3 S^1/3 used for calculating the flood discharges in rivers.

Laceys regime equation is 1/n(r^3/4s^1/3).

10.8r^2/3s^1/3 is laceys theroy.
