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

Question asked is square channel section.
So the wetted perimeter for square channel section is 3d. Hence hydraulic radius = d^2/3d = d/3.
Hydraulic radius of the circular pipe is d/4. So the correct answer is 3/4.
So the wetted perimeter for square channel section is 3d. Hence hydraulic radius = d^2/3d = d/3.
Hydraulic radius of the circular pipe is d/4. So the correct answer is 3/4.

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

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.

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.
