Design of the casing of centrifugal pump should be such as to minimise the________________?
Correct answer: D. Loss of kinetic head
- A. Back flow through impeller
- B. None of these
- C. Loss of static head
- D. Loss of kinetic head
Explanation
The casing gradually converts the impeller's velocity head into pressure head through diffusion, so its design should minimise loss of kinetic head. This improves the pressure recovery and efficiency of the pump.
