Question

A velocity potential function exists only for



(A) steady flow

(B) uniform flow

(C) irrotational flow

(D) compressible flow​

Answer 1

Answer:

B) uniform flow .

hope it will help you

Answer 2

Explanation:

Only if the Curl of the velocity vector is zero,there exists a scalar function (Velocity potential in our case). Curl of velocity vector equal to zero means the flow is irrotational ! Hence,Velocity potential exists only for a irrotational flow !

this is correct ans
