Thermal conduction is the transport of energy in a medium due to a temperature gradient and the physical mechanism is that of random  atomic or molecular activity.The quantity of heat flow through the cross sction of a solid body over time 't' in steady state is governed by the Fourier's law of heat conduction

      Working Formula:

                                                                 Heat conduction through single material sphere is given by

                                       Where the symbols carry their usual meanings

      Description:

                            radial conduction unit

                                            It consist of-

                                                                     1. Insulating housing with disc and lid

                                                                     2. Heater

                                                                     3. cooler

                                                            -The heater is fixed in the center of the bress disc.

                                                            -There is Cu pipe around the disc through which cooling water flows.

                                                            -From above,6 temperature measuring points are fitted.

                                                            -These points stretches radially from the center to the periphery.

                                                The control and dispaly unit has a digital temperature and power dispaly
