The operation of the lube oil cooler, shown in the illustration as item #4, will be characterized by which of the following statements? Illustration MO-0111

Correct Answer: Option B — The temperature of the sea water entering the cooler will be higher when operating with the distiller on line.

When the distiller operates on line, cooling seawater absorbs additional thermal energy, resulting in a higher inlet temperature entering downstream lube oil coolers.
