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 A — The temperature of the sea water entering the cooler will be higher when operating with the distiller on line.

When a distiller is online, it utilizes heat from the cooling system, often reducing the flow rate or increasing the heat load on the sea water circuit. This reduced flow or increased thermal energy absorption results in a higher temperature for the sea water entering the lube oil cooler.
