🔍 Key Concepts

• Heat exchange in a lube oil cooler (hot lube oil on one side, cooler seawater on the other) • Effect of changing seawater flow through the cooler on lube oil temperature • Difference between adjusting an inlet valve vs a discharge valve in a cooling system

💭 Think About

• Which action will increase the seawater flow through the cooler and thus remove more heat from the lube oil? • How does throttling a discharge valve affect flow rate and system backpressure compared with opening it more? • If the lube oil is too hot, do you want more or less cooling water flow through the cooler?

✅ Before You Answer

• Identify which choice would increase seawater flow through the cooler the most effectively. • Eliminate any options that would reduce flow or increase backpressure on the seawater side of the cooler. • Confirm that the chosen action directly improves heat transfer (more cold seawater or better circulation), rather than just increasing lube oil circulation without more cooling.
