The vanes on an impeller are curved away from the direction of rotation so that water moves toward the edge. Which feature is this describing?

Explanation:
This describes the vanes—the blades of the impeller. When the blades are curved away from the direction of rotation, they direct the water outward toward the edge as it spins, which is a backward-curved blade geometry. This shape transfers energy to the water efficiently and sends it toward the outer rim and into the surrounding volute. Shrouds are the enclosing plates that cap the blade stack, volute is the pump housing that collects the flow, and fins isn’t the standard term for these impeller blades.
