Density 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.

As above but with two sets of mica vanes placed in two separate bulbs, blackened in such a way that rotations are in opposite directions.

To show the convection of heat in air. Metal box, 230 x 75 x 75 mm, with sliding glass front and two detachable glass chimneys. Supplied without candles.

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