COMPOSITE WALLS APPARATUS
Demonstrates the thermal conductivity at various heat inputs and different configurations. The apparatus consists of a heater sandwitched between two identical composite slabs. Water cooled heat sinks, to steady state heat transfer condition achieved earlier. Provides MS, Brass and Bakelite plates and necessary meters on control panel.
CRITICAL RADIUS OF INSULATING MATERIAL
To find out critical radius of insulation, ratio of thermal conductivity and outside heat transfer co-efficient. The unit consists of four G. I. pipes provided with plaster of paris insulation on out side surface and heater inside, having separate input control. Input to heaters is measured by common voltmeter& ammeter.
HEAT PIPE DEMONSTRATOR
Demonstrates super conductivity of heat pipe as compared to copper pipe as good conductor of heat and to stainless steel pipe as same material of construction. The unit provides Heat pipe, copper pipe & stainless steel pipe. All the pipes are heated at one end & water tank at other end. To find out isothermal operation of heat pipe as compared to other conductors by use of thermocouples.
HEAT TRANSFER THROUGH LAGGED PIPE
Explains the Thermal conductivity and characteristics of Lagging material ,using three concentric pipes and A heater and two types of lagging materials are filled up. thermocouples and dimmer state measures various temperatures and heat inputs.
UNSTEADY STATE OF HEAT TRANSFER APPARATUS
An example of an unsteady state problem of interest is the heat transfer of a solid body being quenched in a fluid, the apparatus consist of a small cylinder, heated by a hot bath till steady state reaches then quenehed in air or water bath. So, temp of cylinder is a function of time, heating and cooling of cylinder are unsteady.
