🔍 Key Concepts

• Heat transfer in a shell-and-tube lube oil cooler • Effects of fouling (scale/dirt) on temperature vs. pressure in fluid systems • Difference between a restriction on the oil side vs. fouling on the seawater side

💭 Think About

• Think about what happens to heat transfer when the seawater passages slowly become coated with scale and dirt but flow is not completely blocked. • Consider which operating parameter would change first and most noticeably as the cooler becomes less efficient at removing heat from the lube oil. • Ask yourself: would scale on the seawater side directly restrict oil flow, seawater flow, or mainly affect the rate of heat removal?

✅ Before You Answer

• Identify which option reflects a gradual loss of cooling efficiency rather than an immediate mechanical blockage. • Decide whether fouling on the seawater side is more likely to affect temperature or pressure of the lube oil. • Verify which symptoms are usually associated with restricted oil flow versus reduced heat transfer.
