Centrifugal pumps - ANSWER Centrifugal pumps are a type of machine used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy. operating principles - ANSWER Centrifugal pumps operate using kinetic energy to move fluids, utilizing an impeller and and a circular pump casing . The impeller produces fluid velocity and the casing forces the liquid to discharge from the pump, converging velocity to pressure. What type of pump is a non-positive displacement...
