This is a table top unit for observation of evaporation process in a heated tank.

The unit consists of a transparent tank, enclosed at top and bottom. At the bottom of the tank is a small heating cylinder and a special liquid simulating a fire tube heating water in a boiler. The vapor is condensed by a water cooled condenser at the top of the tank and the condensed liquid returns to the bottom for reboiling.

Instruments are provided for measurement of temperatures, pressure, cooling water flow rate, and input power.

  • Observation of evaporation forms.

     

  • Determination of heat transfer efficient.

     

  • Effect of pressure and temperatures on evaporation.
