🔍 Key Concepts

• steam quality and the effects of moisture content on turbine operation • how water slugs affect turbine speed and load, not just hardware erosion • relationship between load on a turbine and its rotational speed when driving a pump

💭 Think About

• When a large amount of water suddenly enters a steam turbine, what happens to the power being transmitted to the pump—does the pump see more load, less load, or a sudden interruption? • If the driven pump suddenly cannot transmit power effectively (for example, due to loss of flow), what typically happens to turbine speed if the governor cannot react instantly? • Which of the options directly relates to a sudden change in turbine speed rather than long-term damage or temperature effects?

✅ Before You Answer

• Distinguish between long‑term damage mechanisms (like erosion, overheating, bearing damage) and immediate dynamic effects (speed/load changes). • Check which option specifically mentions a condition that can quickly follow a sudden disruption of smooth steam flow to the turbine. • Verify which choice is most closely tied to turbine speed control rather than general mechanical wear.
