Head developed by a centrifugal pump depends on its___________________?
Correct answer: C. Both A. and B.
- A. Speed
- B. Impeller diameter
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Centrifugal-pump head varies with impeller speed and diameter; approximately, head is proportional to the square of speed and impeller diameter for comparable conditions. Therefore both speed and impeller diameter affect the developed head.
