Friction Block And Surface Set

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.

Steel fly wheel 100 mm diam.with pulley 20 mm diam. on shaft held in brackets, mounted on base.

Air cooled, four stroke, with operation of valves clearly shown. Mounted on a polished wooden base with schematic diagram, overall height 450 mm approx.
