In case of a vertical tube evaporator, with increase in the liquor level, the___________________?
Correct answer: A. Capacity of the evaporator is decreased
- A. Capacity of the evaporator is decreased
- B. Capacity of the evaporator is increased
- C. True temperature drop increases
- D. Both B. and C.
Explanation
Raising the liquor level in a vertical-tube evaporator increases the hydrostatic pressure and boiling-point elevation, reducing the effective temperature difference and evaporation capacity. Thus, the capacity decreases.
