BEC 010

STUDY OF CONDENSATION

Description Water  in a closed glass chamber is heated by an electric heater and is converted into vapour. This vapour is condensing in drops on one condenser and as a film on another condenser. An air jet blower extracts the air from the condensers. The instruments of this unit make it possible to measure the heat exchanged and to observe the advantages of condensation in drops over condensation as a film. The BEC equipment is delivered complete with instrumentation and includes a technical manual as well as instructions.  Teaching suggested applications* Visual observation of the boiling water and the condensation in drops and as a film. Measurement of the heat flow and the surface heat transfer coefficient for the condensation in drops and film Examination of the relationship between temperature and pressure for the saturated water vapour between 50°C and 100°C Visual demonstration of the effect of air in a condenser Observation of DALTON’s law.

HEAT EXCHANGES UNIT- VISCOUS FLUID /WATER

Description Oil (viscous behavior)  heated by a thermoregulator (closed circuit) goes through an exchanger equipped with concentric and cylindrical tubes where it heats  water that is flowing in an open circuit. The instruments provided with the unit permit measurement of  temperatures and flow rates of the fluids. This allows one to deduce the influence of laminar flow on the coefficient of exchange.  The unit is delivered complete with instrumentation and with technical documentation and instructions.  Teaching suggested applications* Operation of a concentric tube heat exchanger with cocurrent and counter current flow. Determination of the coefficients of exchange for laminar flow in a viscous fluid.
