🔍 Key Concepts

• Centrifugal pump design used for engine cooling water • Effect of impeller vane shape (curved vs straight) on flow characteristics • Difference between tangential vs concentric outlets/housings in pump casings

💭 Think About

• For a cooling water system on a reversing diesel, do you want flow that is very direction-sensitive or relatively uniform regardless of engine rotation? • Which combination of impeller vane shape and casing/housing style tends to give more efficient, smoother flow for liquids like water? • How does a concentric housing vs a volute (tangential) outlet affect the pump’s dependence on direction of rotation?

✅ Before You Answer

• Verify which pump/casing style allows similar performance even if rotation is reversed. • Check which outlet/housing arrangement is typically associated with a volute casing (look for tangential vs concentric). • Confirm which impeller vane shape is commonly used in centrifugal cooling water pumps on marine diesel engines.
