In a centrifugal pump, when the impeller spins, where does the water collect after being discharged?

Answer: C — Volute

In a centrifugal pump, as the impeller spins, it generates centrifugal force that pushes the water outward. After the water is discharged from the impeller, it collects in the volute. The volute is a specially designed part of the pump that provides a gradual expansion of the flow area, allowing the water to slow down and convert kinetic energy into pressure energy. This process helps maintain a continuous flow and directs the water towards the discharge pipe. The volute plays a crucial role in the overall efficiency of the pump, as it helps to evenly distribute the flow and reduce turbulence. By collecting the water in this chamber, the pump ensures that the water can be effectively transmitted through to the discharge pipe where it exits the system.
