The brine level in the second-stage of a flash-type evaporator is determined in part by the feed rate, the rate of evaporation in both stages, and the _______________.
AI Explanation
The correct answer is A) throughput of the brine overboard pump.
The brine level in the second-stage of a flash-type evaporator is determined by the balance between the feed rate, the rate of evaporation in both stages, and the throughput of the brine overboard pump. The brine overboard pump removes concentrated brine from the system, which helps maintain the desired brine level in the second stage. The other options are not directly related to controlling the brine level in the second-stage evaporator.
