It should be 4/3.
As the hydraulic radius of circle = d/3.
Hydraulic radius of square = d/4.
As the hydraulic radius of circle = d/3.
Hydraulic radius of square = d/4.

Answer is 3/4 since the wetted perimeter in case of a square is 3d and not 4d.

Here it is a square channel, not a square pipe so perimeter is only 3d.

Can anyone tell me how the hydraulic radius is 3/D for square?

A is the correct option.
So, R = d/4-d/4 = 1.
So, R = d/4-d/4 = 1.
