Demonstrates experiments with fins in natural and forced convection and various flow rates, various heat inputs and with fins of different material. Unit consist a pin type fin, heated by a heater, blower draws air over the fin,Thermocouple measures temperature. Fins- Brass, Aluminium and M.S.Control panel with necessary instruments, Air flow duct with blower.The unit is provided with antirust an attractive powder coating

To study over all heat transfer coefficient and local heat transfer coefficients in natural convection at various heat transfer rates. Vertical brass pipe heated by heater, the pipe looses heat to atmosphere by natural convection. It is filled in an enclosure to provide undisturbed natural convection currents. Thermocouple to measure local temperature. Control panel with necessary measuring instruments.

To calculate local and over all heat transfer coefficient in forced convection at various air flow rates and various heat flux values. The unit consists of a circular pipe loosing heat by forced convection to air, being forced through it. constant heat flux is added to pipe by heater provided with input control. Thermocouple to measure a various pipe surface temperature and air inlet and outlet of test section. The unit is provided with antirust an attractive powder coating

To determine the specific heat of air at different temperatures air quantity and heater input can be varied. A blower delivers the required quantity air, air passing through the pipe, heated by heater, temp of entering and leaving test section are measured by thermocouples. By knowing heater input and mass flow of air, specific heat of air at constant pressure can be calculated.

To study overall heat transfer coefficient and effect of agitator speed and water flow through coil. a stainless steel vessel, inside which copper tube helical coil is fitted, fluid in the vessel is kept at desired temp, cold fluid picks up heat from surrounding hot fluid. varic to vary agitator speed and to vary input to heaters.
