Measurement of the interfacial area of mass transfer is achieved easily & accurately in case of a ________________ column?
Correct answer: A. Wetted wall
- A. Wetted wall
- B. Packed
- C. Bubble cap plate
- D. Spray
Explanation
In a wetted-wall column, the interfacial area is defined geometrically by the wetted wall, making it easier to measure accurately than the irregular area in packed or plate columns. This known area is also why the column is useful for mass-transfer-coefficient studies.
