Which of the following statements is true concerning centrifugal pumps?

Correct Answer: Option A — A flow is developed by imparting kinetic energy to the fluid by the rotation of an impeller.

Centrifugal pumps operate by converting mechanical energy into kinetic energy through the rotation of an impeller. This velocity is then converted into pressure head within the pump casing. This design is governed by the principles of fluid dynamics and is the standard for most marine liquid transfer applications.
