Topic: Fluid Mechanics
Circulation is defined as the line integral of tangential component of velocity about a
- A. Centre
- B. close contour in a fluid flow
- C. velocity profile
- D. pressure profile
Answer: B. close contour in a fluid flow
Explanation: In fluid mechanics, circulation $\Gamma$ is strictly defined as the line integral of the tangential component of the velocity vector taken around a closed contour in the fluid flow.
