- (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 crosssection
- (D) Average flow occurs at a radial distance of 0.5 r from the centre of the pipe (r = pipe radius)
