Pascal's Law - answer-Pressure on a confined fluid is transmitted undiminished in every direction, acts with equal force on equal areas, and at right angles to the container walls. Series Circuits - answer-If cylinders are hooked in series, the pressure required to lift the first cylinder is affected by the pressure required to life the next cylinder in series circuit. The resultant pressure is called back pressure. Bernoulli's Principle - answer-States that the sum of pressures and ...

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...
