Question

Is laminar flow occurs at lower velocities?

(a) True

(b) False

I had been asked this question during an interview for a job.

Question is taken from Laminar Flow topic in division Incompressible Flow over Airfoils of Aerodynamics

Answer 1

Right choice is (a) True

Explanation: When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid, laminar flow tends to occur at lower velocities, below a threshold at which it becomes turbulent.
