The Correct Answer is B. Because shear stress is maximum at distance r=D/2 from the centre of the pipe.

I think Option B should be correct.

The Correct option is B.
Because velocity is maximum at the centre whereas the shear stress is maximum at the inner surface of pipe.
Because velocity is maximum at the centre whereas the shear stress is maximum at the inner surface of pipe.

1. Velocity distribution is parabolic. That is maximum at the centre.
2. The shear stress distribution is zero at the centre and gradually increased though it the inner surface.
Here, "B" is the correct answer.
2. The shear stress distribution is zero at the centre and gradually increased though it the inner surface.
Here, "B" is the correct answer.

In the case of inviscous flow i.e. ideal flow shear stress distribution is of rectangular shape so answer c is correct.
In case of real flow steady and laminar then option B will be correct.
In case of real flow steady and laminar then option B will be correct.
