The flow of liquid within the impeller of a centrifugal pump is ( ). A. As the blade moves in a circular path B. Moving tangentially relative to the blade C. A combined motion of both circular movement and flow relative to the blade D. Random motion Answer: C
C is a combined flow that involves both circular motion and flow relative to the impeller. However, at the moment water leaves the impeller, it moves tangentially, experiencing centrifugal force; hence it is called a centrifugal pump.
C. Composite motion of both circular motion and flow relative to the blade
