@Piyush your explanation is correct.

Piyush said:   6 years ago
Answer is correct because it is said ""near the wall"" not ""at the wall"".

Yes, at the wall, velocity will be zero but near the wall, velocity will be minimum.

I agree. @Sid.

Asif said:   6 years ago
Yes, velocity at the centre is maximum and at wall 0.

Sid said:   6 years ago
Max at the centre and zero at the walls and min NEAR the walls.

Near the wall, there will be no slip condition so that v=0 at the surface. D this parabolic curve is showing velocity distribution, and as per this velocity is maximum at the center.

Answer is D.

Fluid Velocity in a pipe is maximum at the centre, zero at the wall and minimum near the wall. So option A is absolutely right.

Right answer should be D.

Maximum at the center and zero at the wall surface.

Sharan said:   1 decade ago
The fluid velocity in a pipe changes from zero at the surface because of the no-slip condition to a maximum at the pipe center.
