Q256
In case of laminar flow of fluid through a circular pipe, the
A.
Shear stress over the cross-section is proportional to the distance from the surface of the pipe
B.
Surface of velocity distribution is a paraboloid of revolution, whose volume equals half the volume of circumscribing cylinder
AnswerC.
Velocity profile varies hyperbolically and the shear stress remains constant over the cross-section
D.
Average flow occurs at a radial distance of 0.5 r from the centre of the pipe (r = pipe radius)
