Question 1 of 27070

During high-speed operation of the main turbine propulsion unit, the heat absorbed by the lubricating oil is removed by the __________.

🔍 Key Concepts

• purpose of each lube oil system component (cooler, purifier, sump, distillate cooler) • how heat is actually removed from a circulating oil system • difference between cleaning oil vs cooling oil in turbine systems

💭 Think About

• Which piece of equipment is specifically designed to transfer heat from the lubricating oil to another medium (usually seawater or fresh water)? • Which device operates mainly to remove contaminants like water and sludge, rather than to control temperature? • In a high-speed turbine, where does the lubricating oil go immediately after it has picked up heat from the bearings?

✅ Before You Answer

• Match each choice to its primary function (cooling, purification, venting, distillate cooling). • Ask yourself: which item would normally be found on the lube oil cooling circuit of a turbine system drawing? • Verify which component actually has a heat-exchange surface (tubes, plates, or coils) designed for temperature control.
