The Answer is correct because of the behaviour of shear stress that is one at Maximum at face and minimum at centre in constant throughout all the sections.

It is Zero at centre of pipe

The correct answer is B.

Shear stress across a section varies with r. Hence dp/dx across a section is constant. Hence shear across a section is linear. Hence shear stress is maxed at inside surface of the pipe.

Yes, the distribution diagram is K shaped. Hence, maximum at the inside faces and zero at centre. Option B is correct.

B is correct. I also agree.

Shear stress is minimum at the center and maximum at the face of wall inside the pipe.

Shear stress is maximum at outer face of pipe and zero at the center of pipe of axis.

Answer will be (D) none of these.
As shear stress distribution is minimum at centre and maximum at pipe wall. Don't get confused.
As shear stress distribution is minimum at centre and maximum at pipe wall. Don't get confused.

In a pipe flow friction developed, Which cause velocity not constant throughout the section, so that shear stress never constant through the section. Shear stress proportional to the distance from center of the pipe. As radius 0 shear stress 0, and are maximum, shear stress will be maximum.
