Hope’s Apparatus

Showing internal structure and operating principles of a simple piston air cooled two stroke engine, Mounted on a polished wood base with schematic diagram, overall height 360 mm approx.

For demonstrating the different heat conductivities of five metals by observing the melting of wax.

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.
