A free vortex is formed when water flows out of a vessel through a central hole in the base. The degree of the rotation depends on the initial disturbance. In a free cylindrical vortex, the velocity varies inversely with the distance from the axis of rotation.

Agree @Rohan.

Also in free vertex net torque zero and velocity inverse proposal to radius and opp in forced.

Forced vortex flow in which external torque is required but in free vortex flow no external torque is required to rotate the fluid mass.
