For shear Max at the boundary min at center where as for velocity it is parabolic section.

Asad said:   7 years ago
The Correct Answer is B. Because shear stress is maximum at distance r=D/2 from the centre of the pipe.

Ajayveer said:   7 years ago
I think Option B should be correct.

Hussain Azam said:   7 years ago
The Correct option is B.

Because velocity is maximum at the centre whereas the shear stress is maximum at the inner surface of pipe.

Abahy Dubey said:   6 years ago
Option B is the correct answer.

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.

Shear stress distribution is linear at center is zero and maximum at wall surface.

Here, τ = -dp/dx(r/2).

Nadeem Qadir said:   5 years ago
Shear stress is more at the surface and minimum at center.

Answer should be B.

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.
