🔍 Key Concepts

• Heat exchanger (cooler) pressure relationships between two fluids • Risk and consequences of seawater leaking into lube oil or jacket water systems • Which fluid is more critical to keep clean: seawater, jacket water, or lube oil

💭 Think About

• If a tube in the cooler fails, in which direction do you want any leakage to flow to protect the engine? From seawater to the other fluid, or from the other fluid to seawater? • For the jacket water cooler, which side (seawater or jacket water) should have the higher pressure to best protect the engine’s cooling system? • For the lube oil cooler, which side (seawater or lube oil) should have the higher pressure to avoid serious engine damage and expensive clean-up?

✅ Before You Answer

• For each cooler, decide which fluid must NOT be contaminated and which fluid is easier to lose or discharge. • Remember that fluid will leak from the higher-pressure side to the lower-pressure side if there is a leak. • Check that your chosen option has the pressure relationships arranged so that any leak will send flow away from the critical internal engine fluid and toward the less critical fluid.

Question 1 of 20

Suppose a diesel engine is fitted with sea water-cooled lube oil and jacket water coolers. What statement is true concerning the system operating pressures?

The jacket water pressure is maintained higher than the sea water pressure in the jacket water cooler, and the lube oil pressure is maintained lower than the sea water pressure in the lube oil cooler.

The jacket water pressure is maintained lower than the sea water pressure in the jacket water cooler, and the lube oil pressure is maintained lower than the sea water pressure in the lube oil cooler.

The jacket water pressure is maintained lower than the sea water pressure in the jacket water cooler, and the lube oil pressure is maintained higher than the sea water pressure in the lube oil cooler.
