🔍 Key Concepts

• Behavior of pressure in a closed cooling system when flow is steady vs disrupted • How pump cavitation affects flow and pressure in a liquid system • Which faults would cause a steady high/low pressure rather than a fluctuating one

💭 Think About

• For each choice, ask: would this fault make pressure change back and forth over time, or just move to a new stable value? • Think about what happens to system pressure if air/steam bubbles form and collapse repeatedly in a pump or line. • Consider whether an open vent or a restriction would cause continuous loss or constant backpressure, versus rapid variations on the gauge.

✅ Before You Answer

• Identify which option directly affects the pump’s ability to deliver smooth, continuous flow. • Decide which issues are more likely to cause constant high or low pressure, not fluctuating pressure. • Consider how an open vent in a closed system would affect overall pressure level and whether it would fluctuate or stay low.
