If the path of liquid across the plate is very long as in case of large diameter tower, Murphree efficiency can be _______________ percent?
Correct answer: B. > 100
- A. 100
- B. > 100
- C. < 100
- D. None of these
Explanation
With a long liquid flow path, the liquid composition changes substantially across the tray, so the reference equilibrium vapour composition used in the Murphree definition can make the calculated efficiency exceed 100%. This is an apparent efficiency effect, not a violation of physical mass transfer.
