Question

Vorticity of a fluid is equal to

• A. Rotational component
• B. Half the rotational component
• C. Double the rotational component
• D. One fourth the rotational component

Answer 1

Answer:

C. Double the rotational component

Vorticity of a fluid is the local rotation of a fluid particle and is defined as the ratio of circulation to the area of a closed contour. It is twice the rotational component and equal to the curl of the velocity field.
