🔍 Key Concepts

• Centrifugal pump performance at shutoff (zero flow) • How steam turbine speed is controlled under changing load • What happens to power and temperature in a pump when the discharge is blocked

💭 Think About

• Think about what happens to the flow, head (pressure), and power absorbed by a centrifugal pump when the discharge valve is gradually closed to zero flow. • Consider how a governed steam turbine reacts when the load (power demand) from the pump changes—does it naturally speed up, slow down, or stay nearly constant? • At zero flow, what happens inside the pump casing to the liquid in terms of recirculation and heating?

✅ Before You Answer

• Verify whether a centrifugal pump at shutoff (discharge valve closed) still spins and continues to impart energy to the liquid. • Check if the turbine governor tends to hold speed nearly constant when load changes, rather than allowing large speed swings. • Confirm whether a pump with no discharge flow is more likely to run hotter or cooler over time.
