Noun
One who, or that which, impels.

An impeller that has been operating under a suction cavitation condition can have large chunks of material removed from its face or very small bits of material removed, causing the impeller to look spongelike. Source: Internet
Cavitation in pumps may occur in two different forms: Suction cavitation Suction cavitation occurs when the pump suction is under a low-pressure/high-vacuum condition where the liquid turns into a vapor at the eye of the pump impeller. Source: Internet
Consequently, one side of the double-suction impeller receives more flow at a higher flow velocity and pressure while the starved side receives a highly turbulent and potentially damaging flow. Source: Internet
Hooker 1984, p. 45. The function of the supercharger is to compress the fuel/air mixture entering the engine cylinders; any pressure loss to the impeller (also called the rotor) would impair the supercharger's efficiency. Source: Internet
It is usually achieved through impeller design or by forcing the mixture through an annular opening that has a narrow entrance orifice with a much larger exit orifice. Source: Internet
