Fluid flow in a/an ______________ is an example of pressure flow?
Correct answer: B. Pipe
- A. Partially filled pipeline
- B. Pipe
- C. Open channel
- D. River
Explanation
A completely filled pipe carries pressure flow because the fluid is confined and its motion is driven by a pressure gradient. Open channels, rivers, and partially filled pipes have a free surface and are primarily gravity-driven flows.
