OBJECTIVE: The purpose of this experiment is to determine the characteristics of a centrifugal pump and use the concepts of similitude to generalize its performance. Similitude results will be compared with the real pump characteristics. Also, net positive suction head required for the pump is determined. 2. EXPERIMENTAL SETUP Pumps are turbo machines transferring mechanical energy into fluid energy. The energy of the fluid is increased through the pump. This energy is supplied by the impeller, which in turn is driven by an electric motor or some other drive. In this experiment centrifugal pump is used (Domak SLG1” 1 HP). In this experiment, pump system performance will be determined. The pump system is schematically described in Figure-1 the flow rate is adjusted from the discharge valve, located after the pump. Bourdon gages are mounted at the suction and discharge sides of the pump. The flow rate is measured using rotameter (variable area flow meter). A rotameter is a vertically installed device, which operates when the upward fluid drag on the float is balanced by the weight of the float. The float operates in a diverging tube. Float and the tube geometry and material depend on the range of operation of the rotameter. Power analyzer is used for measuring, volt, amper and power factor which are used for obtaining the power input to the motor of the centrifugal pump. used for obtaining the power input to the motor of the centrifugal pump....
