A fluid rotates with an angular velocity w about the z-axis. The direction of rotation is related to the z-axis by the rigrt hand screw rule.
a) Find the velocity v of a point in the fluid, and show that
curl v = 2w_k
b) If now w is a function of the radius r, show that curl v = zero if w= constant/r square
