Question 1 of 27070

The basic function of the centrifugal pump impeller is to __________.

🔍 Key Concepts

• centrifugal pump impeller purpose in the pumping cycle • difference between pressure and velocity in a fluid • where in the pump casing pressure is usually developed

💭 Think About

• Think about what happens to the fluid exactly as it leaves the rotating impeller vanes – does its speed or its pressure change first? • Ask yourself: in a centrifugal pump, is most of the pressure rise created by the impeller itself, or by what happens to the fast-moving fluid in the casing/volute afterward? • Which option best describes the immediate energy change the impeller gives to the liquid, before it reaches the diffuser or volute?

✅ Before You Answer

• Be clear on the distinction between increasing velocity versus increasing pressure – they are related but not identical. • Consider where kinetic energy is converted to pressure (potential) energy in a centrifugal pump – at the impeller or mainly in the volute/diffuser? • Eliminate any choice that describes a function normally handled by priming systems or air separators, rather than the impeller itself.
