🔍 Key Concepts

• Centrifugal pump operating conditions (normal flow vs. shutoff/head against a closed discharge valve) • Difference between capacity (flow rate), efficiency, and horsepower in pump terminology • What happens to liquid movement when the discharge side is completely blocked

💭 Think About

• Think about what physically happens inside the pump when the discharge valve is completely closed—does any liquid actually leave the pump? • Which of the four choices describes a condition that is guaranteed when there is no fluid leaving the discharge? • For each choice, ask: would this always be true at a closed discharge, or could it vary depending on the pump design and operating point?

✅ Before You Answer

• Be clear that capacity in pump language means volumetric flow rate out of the pump (e.g., gallons per minute). • Remember that efficiency is the ratio of useful output (flow × head) to power input—if there is no flow, what happens to useful output? • Check whether internal slippage and horsepower rating are fixed at shutoff for all centrifugal pumps, or if they can differ by design, making them unlikely to be the universally correct statement.
