The specialized plate that delivers the motive force to the fluid in a centrifugal pump is called what?

Correct Answer: Option B — Impeller

The impeller is the rotating component of a centrifugal pump that imparts kinetic energy to the fluid. As it spins, centrifugal force accelerates the liquid from the eye of the impeller toward the casing, converting velocity into pressure head, which is the fundamental operational principle of all centrifugal pumping machinery.
