Good design of the casing of a centrifugal pump aims at minimising the __________________________?
Correct answer: C. Kinetic energy loss
- A. Cavitation
- B. Frictional losses
- C. Kinetic energy loss
- D. Static head
Explanation
The casing of a centrifugal pump converts much of the impeller discharge velocity into pressure through gradual deceleration. A well-designed casing therefore minimises kinetic-energy losses rather than static head.
