A centrifugal pump designed to pump water is employed to pump a more viscous oil. In the later case, the pump_________________?
Correct answer: A. All A., B. and C.
- A. All A., B. and C.
- B. Capacity is reduced
- C. Requires more power
- D. Develops a lower head
Explanation
Higher viscosity increases internal friction and reduces a centrifugal pump's capacity and developed head, while increasing the power needed for operation. These three effects are summarized by the combined option.
