Question

The flow in which the flow parameters change from one point to other is called _________

(a) uniform flow

(b) non-uniform flow

(c) steady flow

(d) linear flow

The question was posed to me in an interview.

Origin of the question is Uniform Flow in section Inviscid & Incompressible Flow of Aerodynamics

Answer 1

Correct option is (b) non-uniform flow

Explanation: The flow in which all the hydrostatic parameters change from one point to other is called non-uniform flow. The changes may be in direction of flow or in the direction perpendicular to the flow. The example of the changes perpendicular to the flow is the flow over the solid bodies.
