Q

Which of the following statements is true concerning centrifugal pumps?

🔍 Key Concepts

• Basic operating principle of centrifugal pumps (how they move liquid) • Difference between starting procedures for positive displacement vs centrifugal pumps • Effect of fluid viscosity on centrifugal pump efficiency

💭 Think About

• Think about what physically happens inside a centrifugal pump when the impeller spins. How does that motion affect the liquid? • Consider whether centrifugal pumps must be installed only one way, or if they can be oriented differently depending on design. • Ask yourself: do centrifugal pumps perform better with thin (low-viscosity) liquids or thick (high-viscosity) liquids, and how does that compare with gear or screw pumps?

✅ Before You Answer

• Verify how impeller rotation creates flow and pressure in a centrifugal pump. • Check recommended start-up procedure: is the discharge valve normally open or closed when starting a centrifugal pump? • Confirm whether high-viscosity fluids are generally recommended or not for centrifugal pumps in standard marine applications.
