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

I think the answer is option A.

@All.
But remember the question says that the square section is running full to the wetted perimeter should be 4D and not 3D and by this, the answer should be A.

D is correct, i.e R = A\P.

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.

Agree, D is the correct answer.

For circular pipe hydraulic mean depth = d/4.
For the square section of channel hydraulic mean depth=d/3.
Ratio of the circle to square= 3/4.
For the square section of channel hydraulic mean depth=d/3.
Ratio of the circle to square= 3/4.

D is the correct answer. I agree.

Both hydraulic radius is not same.
Circular hydraulic radius = D/4 and
Square Hydraulic radius = 3/D.
So Ans is D.
Circular hydraulic radius = D/4 and
Square Hydraulic radius = 3/D.
So Ans is D.

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