Unsteady non-uniform flow is represented by flow through a/an_________________?
Correct answer: C. Expanding tube at increasing rate
- A. Long pipe at constant rate
- B. Long pipe at decreasing rate
- C. Expanding tube at increasing rate
- D. Expanding tube at constant rate
Explanation
Unsteady flow changes with time, while non-uniform flow changes with position. An expanding tube gives spatial variation and an increasing flow rate gives temporal variation, so it represents both.
