Expansion Apparatus

To show conversion of mechanical energy into electrical energy. Turbine with transparent cover, inlet and outlet tubes directly connected to a dynamo. Fitted on base.

This simple unit can help the student understand the operating principle of pump and turbine. The unit consists of a rotor attached to a pulley via a shaft. It also includes 3 metal nozzles and a stopcock. When driven by a motor, the unit works as a pump, raising the water to higher potential energy. Whereas when the rotor is made to rotate by flowing water, the unit acts as a turbine.
