If a tube should leak in an operating main steam turbine lube oil cooler, the water will not immediately contaminate the oil because the __________.

🔍 Key Concepts

• Pressure differential between lube oil system and cooling water system • Direction that fluid will flow through a leak when two systems are at different pressures • Normal operating pressures of main lube oil systems versus circulating water systems in a steam turbine lube oil cooler

💭 Think About

• In a leaking tube between two fluids, which fluid moves into which, and what determines the direction of flow? • Under normal turbine operating conditions, which system (oil or water) is typically maintained at the higher pressure, and why might that be intentional? • Which option describes a continuous condition that would prevent immediate contamination, rather than a one-time action by a valve or pump?

✅ Before You Answer

• Compare normal oil pressure to normal cooling water pressure in a main turbine lube oil cooler system • Decide which answer describes an inherent pressure relationship, not a specific device that may or may not act • Ask whether any of the listed valves or pump actions would actually occur automatically just because a tube begins to leak
