Question 1 of 27070

In some lube oil systems, the temperature of the lube oil downstream from the lube oil cooler is directly regulated by __________.

🔍 Key Concepts

• Lube oil temperature control methods in closed-loop systems • Role of a thermostatic valve versus a cooler alone • Difference between heat generation in bearings and active temperature regulation

💭 Think About

• Which component in a lube oil system can actively adjust flow path or flow rate in response to temperature changes? • Do the bearings or seawater actually "control" temperature, or do they just influence how much heat is added/removed? • Think about what must happen to the oil flow when it is too cold versus when it is too hot after the cooler.

✅ Before You Answer

• Identify which option involves an automatic control device that reacts directly to oil temperature. • Eliminate any choices that only describe operating conditions (speed, seawater temperature, heat carried away) rather than a specific regulating mechanism. • Confirm which option changes the proportion of oil through vs. around the cooler to maintain a set outlet temperature.

In some lube oil systems, the temperature of the lube oil downstream from the lube oil cooler is directly regulated by __________.

a thermostatically controlled valve which bypasses oil around the cooler

the amount of latent heat that the oil carries away from the bearings

the ambient sea water temperature

The operating speed range of the equipment
