Learn from the advanced practices of the *Brothers section; there are rewards for correct answers – any answer earns a reward, allowing us to grow and mature through these Q&A sessions. Brief answer: Working principle of a centrifugal pump: Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge, gaining energy in the process, and then exits the outer edge of the impeller at high speed into the volute casing. In the volute, the liquid slows down as the flow channel widens, with part of its kinetic energy being converted into static pressure energy, which is then discharged from the pipe at a higher pressure. As the liquid flows from the center of the impeller toward the outer edge, a vacuum is created at the center of the impeller. Since the pressure above the liquid level in the reservoir is greater than the pressure at the pump inlet, the liquid is continuously forced into the impeller. As the impeller keeps rotating, the liquid is continuously drawn in and discharged.
