For a gravity type lube oil system, a remote pressure sensing device is installed at the point of highest static head pressure on the main unit to enable the watch engineer to __________. be certain that the bearings are being adequately lubricated determine if there is sufficient lube oil pressure to the main engine

🔍 Key Concepts

• Gravity lube oil system operation and what "highest static head" means • Difference between local bearing lubrication vs overall system pressure to the main engine • What a remote pressure sensing device actually measures and where that reading applies

💭 Think About

• Ask yourself: If the sensor is at the point of highest static head pressure, what part of the system is that actually representative of—the bearings themselves, or the supply pressure at the main engine inlet? • Consider whether a single pressure reading at one point can directly confirm bearing lubrication, or if it only indicates conditions at that sensing point. • Think about why an engineer would want this reading in the control room: is it mainly to know about engine supply pressure, bearing condition, or both?

✅ Before You Answer

• Verify what information pressure alone can and cannot give you about bearing lubrication (think: flow vs pressure). • Check whether the highest static head pressure point is necessarily the same as the most critical bearing location. • Confirm whether the device is intended to show system supply pressure to the engine or actual conditions at the bearings.
