The velocity for subsonic flow in a pipeline_______________?
Correct answer: A. Increases in the downstream direction
- A. Increases in the downstream direction
- B. Is constant
- C. Decreases in the downstream direction
- D. Is independent of the area of flow
Explanation
For subsonic compressible flow in a pipeline, friction causes the fluid to accelerate downstream toward sonic conditions, so its velocity increases. This is opposite to the usual frictional trend for supersonic flow.
