🔍 Key Concepts

• Centrifugal pump impeller design and how vane shape affects fluid acceleration • Relationship between number of stages and discharge velocity when overall diameter and (nearly) speed are fixed • Effect of curved vs straight vanes on directing flow and reducing shock losses

💭 Think About

• If diameter, width, and (mostly) speed are fixed, what design feature still allows you to increase the velocity given to the liquid? • How do curved vanes change the direction and smoothness of flow compared to straight vanes, and what does that do to exit velocity? • What is the impact of adding stages or multiple impellers if the rotational speed must be reduced to 90%?

✅ Before You Answer

• Compare how flow guidance (straight vs curved vs stepped curved vanes) affects energy transfer per unit mass of liquid • Consider whether adding more impellers at a lower speed always increases discharge velocity when diameter is unchanged • Think about which design will give the highest absolute exit velocity at the impeller tips, not just higher pressure or head
