Topic: Fluid Mechanics

Multi stage centrifugal pumps are used for

  • A. high discharge
  • B. high head and high discharge
  • C. high pressure
  • D. high efficiency

Answer: C. high pressure

Explanation: In multi-stage centrifugal pumps, several impellers are usually arranged in series. The discharge fluid from one impeller is fed to the suction of the next, meaning the head (and therefore pressure) increases at each stage while maintaining the same discharge. Hence, they are designed to produce high pressure.
