Excluding line losses, how many distinct pressure drops will occur as sea water flows through all the heat exchangers in the cooling system shown in the illustration? Illustration MO-0111
AI Explanation
The correct answer is C) 5 distinct pressure drops.
As sea water flows through the cooling system, it will experience pressure drops across each of the heat exchangers. Excluding line losses, there will be 5 distinct pressure drops: one each across the main engine heat exchanger, the lube oil cooler, the fuel oil cooler, the air compressor cooler, and the generator cooler.
The other answer choices are incorrect because 3 pressure drops is too few, 4 pressure drops is missing one of the coolers, and 6 pressure drops would include additional unnecessary pressure drops.
