The correct answer is 'maximum at the inside of the surface'.
In a viscous fluid flowing through a circular pipe, the shear stress is zero at the centre of the pipe and increases linearly with radial distance, reaching its maximum value at the pipe wall (the inside surface of the pipe).

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).

Shear stress is maximum at the pipe faces and will be minimum at the center. Velocity will be max at the center and minimum at the face of pipe.

The answer is correct; the velocity is maximum @ the centre hence the shear stress being proportional to the velocity gradient is also maximum.

Shear stress is minimum in center and maximum at face.

In circular pipe Shear stress is minimum at center and maximum at face inside the pipe because it varies with are i.e radius keeping dp/dx is constant but in case of velocity i.e velocity is maximum at center and minimum at face inside the pipe.
Hence answer should be B.
Hence answer should be B.
