What can definitely be said about the tube-flow in the diagram below?

What can definitely be said about the tube-flow in the diagram below? Correct Answer Flow is laminar

Explanation:

Laminar Flow: Laminar flow is the flow in which fluid particles flow in layers. Each layer moves smoothly past the adjacent layer with little or no intermixing. There is no intermingling of fluid particles across the cross-section. So laminar flow resembles streamline flow.

Laminar flow through a circular pipe follows parabolic velocity distribution.

From the above diagram, we can see that the velocity distribution in laminar flow is parabolic and the velocity distribution in Turbulent flow is Logarithmic. As in the question figure the velocity distribution parabolic, Hence the given flow is laminar.

Additional Information

For the flow through a circular pipe,

Laminar flow – Reynold’s Number is less than 2000

Turbulent Flow – Reynold’s Number is greater than 4000

Transition Flow – Reynold’s Number is between 2000 to 4000
