Question

If the velocity at a point is given as 3xi + 4 y j, then the vorticity at point (2,3) is units.

• A. 0

Answer 1

The correct option is A 0

V = 3xi + 4y j
$\therefore u=3x$ and v = 4y
$\frac{\partial u}{\partial y}=0$
$\frac{\partial v}{\partial x}=0$
$\therefore$ Vorticity $=|\frac{\partial v}{\partial x}-\frac{\partial u}{\partial y}|=0$
