Which of the following is not the function of a volute casing provided in a centrifugal pump ?
Correct answer: E. To increase the pump discharge rate
- A. To reduce the head loss in discharge
- B. To increase the pump efficiency
- C. To collect liquid from the periphery of the impeller and to transmit it to the delivery pipe at
- D. constant velocity
- E. To increase the pump discharge rate
Explanation
A volute collects liquid leaving the impeller and converts part of its velocity head into pressure head, improving recovery and efficiency. It does not independently increase the pump discharge rate, which is mainly determined by the pump and system characteristics.
