Question

The existence of velocity potential in fluid flow indicates that

Answer 1

Answer:

The existence of velocity potential implies that the fluid is irrotational.

Explanation:

• As we know the curl of a gradient of a scalar function is equal to zero.
• When the curl of the velocity vector is zero, a scalar function exists.
• The curl of the velocity vector equal to '0' means the fluid is irrotational.
• That means velocity potential is for the rotational flow.
