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 B) the 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 the concentrated brine from the second-stage, which helps maintain the desired brine level. The other options, such as the steam flow rate, the capacity of the distillate pump, or the feed heater level, do not directly affect the brine level in the second-stage.
