🔍 Key Concepts

• Energy conversion inside a centrifugal pump (from velocity to pressure) • Role of the impeller versus the volute • Where in the pump the liquid changes direction and speed

💭 Think About

• Think about which component actually spins and which one is a stationary passage in the pump casing. • Ask yourself: where is the fluid gaining speed, and where is that speed turned into pressure? • Consider which part of the pump is shaped to gradually slow the fluid down and increase pressure.

✅ Before You Answer

• Identify which component directly adds velocity to the liquid. • Identify which component is designed as a gradually expanding passage around the impeller. • Confirm which part is responsible for converting kinetic energy (velocity head) into pressure energy (pressure head).
