The ratio of Murphree plate efficiency to point efficiency is always > 1 in a _______________ flow model?
Correct answer: A. Plug
- A. Plug
- B. Perfectly mixed
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
For plug flow across a plate, the driving force varies along the flow path, and the resulting Murphree efficiency is greater than the local point efficiency. In a perfectly mixed model, the driving force is uniform, so this ratio does not exceed one in the same way.
