Referring to the illustrated motor ship fresh water cooling system drawing, what statement is true concerning the evaporator? Illustration MP-CW-06
AI Explanation
The correct answer is C.
The evaporator uses heat recovered from the main engine cooling water as a heat source to generate fresh water, and it is piped in series with and prior to the jacket water cooler. This is the typical configuration for a motor ship fresh water cooling system, where the engine cooling water provides the heat source for the evaporator to produce fresh water, which is then used in the cooling system.
The other answer choices are incorrect because: A) the evaporator is not piped in series after the jacket water cooler, B) the evaporator does not use heat from the jacket water cooler, and D) the evaporator is not piped in parallel with the jacket water cooler.
