If both the shell-and-tube lube oil cooler and shell-and-tube jacket water cooler of a diesel engine are sea water-cooled, what statement is true?

🔍 Key Concepts

• Shell-and-tube heat exchanger flow paths (which fluid usually goes in tubes vs. shell) • Effects of corrosion and cleanliness on choosing the sea water side • Relative pressure and importance of lube oil vs. jacket water circuits

💭 Think About

• Between lube oil, jacket water, and sea water, which fluid is the most corrosive and dirtiest, and where would you want that fluid (tubes or shell)? • Which fluid (lube oil or jacket water) is more critical to protect from contamination if a leak develops, and how does that affect where sea water should go? • In typical marine practice, which side (tube or shell) is easier to mechanically clean, inspect, and replace when dealing with sea water?

✅ Before You Answer

• Be clear on what usually goes through tubes in sea water-cooled exchangers on ships. • Consider which system (lube oil vs. jacket water) can tolerate slightly higher risk of contamination in case of tube failure. • Verify in your mental picture that your chosen option has sea water on the more maintainable side (easier to clean and retube).
