Shear stress distribution is linear in a pipe with max at its inner face and zero at the centre.

It is min at centre and max at the boundary.

I think the correct answer is B.
Jagmohan said:

Shear stress is minimum at the centre.

Answer B is right because shear stress varies linearly from the centre of the pipe to the boundary.
It Means zero shear stress at centre & Maximum at the boundary.
It Means zero shear stress at centre & Maximum at the boundary.

Actually, shear stress is max at inside the surface of pipe and min at the centre but distribution of shear stress is linear. So answer is (C).

As it is a viscous liquid it offers some resistance. So, shear stress will be min. At centre and max. At surface of the pipe. So, the answer should be B. If it is non-viscous fluid then answer is correct.

Stress increases linearly with distance from the centre,
i.e min at centre and max at the boundary of the pipe.
i.e min at centre and max at the boundary of the pipe.

Answer 'A' because shear stress is maxed at faces n min at center as viscous flow is nothing but laminar flow.

Answer should be D because shear stress is 0 at centre and maximum at surface not inside the surface.
