Theory

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 section of a solid body over time 't' in a 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
