🔍 Key Concepts

• Centrifugal pump impeller design – open vs. closed impellers • The meaning of the impeller eye and vane tips • How liquid flows through an impeller and what side walls (shrouds) do

💭 Think About

• Think about the physical difference you would see if you looked at an open impeller versus a closed impeller – what extra pieces of metal are added on a closed impeller? • Which answer choice describes an actual structural feature you could point to with your finger, rather than a performance characteristic that could vary? • Which choice describes something that would be true for all closed impellers by definition, not just for certain designs or operating conditions?

✅ Before You Answer

• Check which option clearly describes side walls or shrouds that change how the vanes are enclosed. • Verify that the option you choose is a defining construction feature, not just a possible side effect of design (like size of the eye or venting). • Eliminate any option that talks about flow direction or venting unless those are part of the basic construction of a closed impeller.
