Have you ever seen how an impeller works in a pump?

Yeah, it’s fascinating how it moves the water around.

I was reading about how different designs of impellers can affect efficiency.

That makes sense; I guess the shape really matters for performance.

Root Explanation

Impeller → It is formed from "in-" (meaning into) and "pellere" (meaning to drive or push). The word describes a device that drives or pushes something into motion.

Memory Tip

Think of something that 'drives' ('pellere') something 'into' ('in-') motion — that's what an impeller does.
