Question:medium

The fluid coming into the centrifugal pump is accelerated by

Show Hint

The heart of a centrifugal pump is the impeller.
Its job is to spin rapidly and throw the fluid outwards, giving it high velocity (kinetic energy).
The casing (volute) then slows the fluid down, converting this velocity into pressure.

  • Nozzle
  • Governer
  • Throttle
  • Impeller
Show Solution

The Correct Option is D

Solution and Explanation

Step 1: Understanding the Question:
Which component accelerates fluid in centrifugal pump?

Step 2: Key Component (Alternate):
Impeller with backward-curved vanes imparts kinetic energy. Casing (volute/diffuser) converts KE to pressure.

Step 3: Detailed Explanation:
Fluid enters eye, flung outward by vanes at high velocity. Nozzle accelerates by area reduction (opposite). Governor controls speed. Throttle valve controls flow.

Step 4: Final Answer:
Impeller.
