Stream function:-
It is defined as the scalar function of space and time, such that its partial derivative with respect to any direction gives the velocity component at right angles to that direction.
r: white; color: red; font-family: georgia, serif;">properties of stream function.
i) If stream function exists , it is a possible case of fluid flow.
ii) If stream function satisfies the laplace equation is a possible case of irrotational flow.
Potential function:-
It is defined as a scalar function of time and space such that its negative derivative with respect to any direction gives the fluid velocity in that direction.

properties of velocity potential function.
- If the velocity potential function exists , it is a possible case of irrotational flow.
- Lines of constant velocity potential function and lines of constant stream function are mutually orthogonal.
