Question

The velocity profile of the Couette flow is _______

(a) Quadratic

(b) Constant

(c) Linear

(d) Zero

This question was addressed to me in an international level competition.

I'm obligated to ask this question of Navier-Stokes Equations of Motion topic in section Fluid Dynamics of Fluid Mechanics

Answer 1

Correct option is (c) Linear

Best explanation: Couette flow is a flow of viscous fluid in the space between two surfaces. One surface moves tangentially with respect to the other. The configuration often takes the form of the two parallel plates or the gaps in between two cylinders.
