Thermal conductivity is an important thermo - physical property of conducting materials, by virtue of which the material conducts the heat energy through it.
The thermal conductivity for a given material depends on its state and it varies with direction, structure, humidity, pressure and temperature change.
Thermal energy can be transported in solids by two means. Transport of free electrons. Thus in hotter portion of the solid, the atoms which have larger vibration energy, transfer a part of its energy to the neighboring low energy molecules and so on throughout the whole length of the body.
The metal rod of brass is inserted into hole so that when power supplied to heater, heat transfer will take place from the base to another end.
The power supply to heat may be adjusted to desire quantity by means of electronic controlled circuit for that one rotary switch is provided on the control panel. Electric power input can be measured by using digital voltmeter and ammeter multiplier.
Thermal Conductivity of Rod Procedure: Switch on the power supply and adjust voltage and current so as to allow some watts input to heater coil. Wait for steady state.
Steady state can be observed by the temperature reading at one or all points on the surface of the metal rod. Steady state is reached when these temperatures stop changing with time.
Under steady state conditions note the temperature of each point on the surface of the rod as well as temperature of surrounding. Repeat above procedure for several power input.Tips for sublimation printing using Astex Heat Transfer Machines, Wasatch Softrip Software and Epson Large Format Printers with Sawgrass Sublimation Inks.
