With diminishing cross-sectional area in case of subsonic flow in a converging nozzle, the____________________?
Correct answer: C. Both A. & B.
- A. Velocity increases
- B. Pressure decreases
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
For subsonic flow through a converging nozzle, continuity requires velocity to rise as area falls, and Bernoulli’s relation then gives a pressure drop. Thus both velocity increases and pressure decreases.
