Answer 2

The correct answer for the ratio of average fluid velocity to the maximum velocity for laminar flow of Newtonian fluid through a smooth round pipe is 0.5.

• For a fully developed laminar viscous flow through a circular pipe, the maximum velocity is equal to twice the average velocity.
• For turbulent flow, the ratio will be 0.75.
• For turbulent flow with the Reynolds number of 1000000, the ratio will be 0.87.
