Which of the following statements is true concerning lube oil coolers?

🔍 Key Concepts

• Heat exchanger basics – how shell-and-tube coolers are arranged for oil vs. water • Pressure relationships between lubricating oil and cooling water to prevent contamination • What happens if a tube leaks in a lube oil cooler

💭 Think About

• If a tube in the cooler fails, which fluid do engineers MOST want to keep from entering the lubricating oil system? Think about engine protection. • In normal operation, which fluid (oil or water) is usually run at the higher pressure, and why does that choice make sense for safety and cleanliness? • Consider whether magnets in tube sheets are common practice, and think about the relative temperatures of lube oil and cooling water in an operating engine.

✅ Before You Answer

• Be clear which side (oil or water) is more critical to keep clean if leakage occurs. • Verify how differential pressure across the cooler is normally arranged to control the direction of any leakage. • Double-check typical operating temperatures of lube oil versus jacket cooling water in marine diesel engines.

The temperature of the oil is less than that of the cooling water.

The pressure of the oil is greater than that of the cooling water.

The pressure of the oil is less than that of the cooling water.
