🔍 Key Concepts

• paths of water ingress into lube oil systems • how lube oil coolers are constructed and where water flows • what functions steam gland seals and tank/casing vents actually perform

💭 Think About

• For each option, ask yourself: Is there a realistic way for water to physically mix with the lube oil at that point? Trace the flow paths. • Think about which systems use water as a cooling medium in close proximity to oil, and which systems mainly deal with steam or air, not liquid water. • Consider whether a component that is secured (out of service) can still be a source of contamination if it has a failure, or if flow paths are isolated.

✅ Before You Answer

• Check which components have water on one side and oil on the other, separated only by tubes or a heat-exchanger surface. • Verify what actually passes through steam sealed turbine glands (is it liquid water, steam, or air?) • Confirm what vents on tanks and gear casings are designed to pass under normal operation (air, vapor, or water?).
