Topic: Fluid Mechanics
The flow of a fluid in a pipe takes place from
- A. Higher level to lower level
- B. Small end to large end
- C. Higher pressure to lower pressure
- D. Higher energy to lower energy
Answer: D. Higher energy to lower energy
Explanation: Fluid flows from a region of higher energy to lower energy and not necessarily from higher pressure to lower pressure. Flow from a low-pressure region to a high-pressure region is possible if the sum of potential, pressure, and kinetic energy is favorable.
