Identify the processes of vorticity:

(A) Acceleration
(B) Frictional influence
(C) Roughness
(D) Rotation
(E) Angular velocity

Choose the correct answer from the options given below:

Correct option is C

Rotation (D) and Angular Velocity (E) are directly related to vorticity since vorticity is mathematically defined as the curl (∇ × V) of the velocity field.

1. Vorticity is a measure of the rotation of fluid particles in a flow field.
2. Mathematical Expression: Vorticity () = ∇ × V (the curl of velocity).
3. High vorticity regions indicate strong rotational motion, as seen in cyclones and tornadoes.
4. Angular velocity is a component of vorticity since it measures the rate of rotation.
5. Vorticity is important in meteorology, aerodynamics, and fluid mechanics.
6. Kelvin's Circulation Theorem describes the conservation of vorticity in inviscid flows.
