Question 113General Subjects - Assistant Engineer

The correct answer is C) It supplies the operating medium used in the removal of the distillate. The water supply through item "P" in the illustration is typically used to supply feed water to the evaporator, as well as the operating medium used in the removal of the brine and air/non-condensable gases. However, it does not supply the operating medium for the removal of the distillate, as that is a separate process. The distillate is the purified water that is the end product of the evaporation process, and its removal is handled through a different mechanism. The other answer choices are incorrect because they describe functions that are accurately associated with the water supply through item "P" in the illustration.
