from the surface of the thermocouple plus four glass thermometers, a wattmeter, a manometer and a water flow meter
horizontally mounted heating element immersed in a liquid. Heat input can be varied to control heat
flow and, therefore, boiling mode.
At the top of the cylinder is a coil through which cooling water flows. It condenses the steam produced
heat supply and the resulting liquid returns to the bottom
re-evaporation cylinder. The cooling control of the water flow maintains a constant pressure during the experiment.
These include all relevant heat transfer calculations.
For student safety, the unit is equipped with both overloads and residual current switches. High pressure cut-off and internal safety valve prevent safe pressure
