Solution

The correct option is C 1 and 3
(c)
Stream function is a consequence of continuity equation. Vorticity is defined as

Ω=×V=2ω

for irrotational flow Ω=0

The velocity potential function is derived from the condition of irrotationality. Thus in rotational flow there will be non-zero vorticity and velocity potential function can not be defined.
