Mass Transfer - Engineering
Q1: When the liquid over a plate is of uniform concentration, thenA Murphree efficiency > point efficiency.
B Murphree efficiency < point efficiency.
C Murphree efficiency = point efficiency.
D Murphree efficiency ≠ point efficiency.
ANS:C - Murphree efficiency = point efficiency. Your explanation is correct! When the liquid over a plate is of uniform concentration, there is no mass transfer occurring between the liquid and vapor phases on that plate, leading to equal values for both Murphree efficiency (𝜂𝑀ηM) and point efficiency (𝜂𝑝ηp). This is because the vapor and liquid leaving the plate are in equilibrium, resulting in no deviation between the theoretical and actual separation efficiencies. Well done! Your explanation provides a clear understanding of the relationship between uniform liquid concentration and the equality of Murphree and point efficiencies in a distillation column. |
