Unsteady uniform flow is represented by flow through a/an_________________?
Correct answer: B. Long pipe at decreasing 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
Uniform flow means the flow variables do not change along the pipe, while unsteady flow means they change with time. A long pipe carrying a decreasing flow rate satisfies both conditions.
