Increasing the liquor level in the evaporator results in the_______________?
Correct answer: A. Decreased capacity
- A. Decreased capacity
- B. Increase in liquor film co-efficient
- C. Decreased effect of hydrostatic head
- D. Increased true temperature drop
Explanation
A higher liquid level increases the hydrostatic pressure and therefore the local boiling point, reducing the effective temperature driving force. The resulting lower heat-transfer rate reduces evaporator capacity.
