A centrifugal pump:

A centrifugal pump:

• A. Takes advantage of incoming pressure
• B. Increases the velocity of the water only
• C. Pushes water without considering incoming pressure
• D. Requires gravity to operate

Answer: (A)

A centrifugal pump operates by taking energy from a driven impeller to add velocity to the fluid and then convert that velocity into higher discharge pressure, using the existing pressure at the inlet to move water through the system. Water enters with suction pressure; the spinning impeller speeds it up, and the pump casing (diffuser/volute) smooths and converts much of that velocity into pressure so water can be pushed out against system demands. It does not rely on gravity to function, nor does it push water by increasing velocity alone—the goal is to raise the fluid’s pressure (head) to meet the discharge requirements, starting from the incoming pressure.
