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
(C) 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)
