Project Summary

The experiment unit is for studying linear heat conduction along a solid bar of uniform cross sectional area. The bar has an electric heater or heat source at one end to generate thermal energy. The maximum power input for the heater is 100W. There is a heat sink at the other end of the bar. There is a thermal switch next to the heater in the base unit to switch off the heater upon over-heating. There are seven equally spaced thermocouples along the length of the bar to measure temperature. The thermocouples are of K-type with an accuracy of ± 0.30C. The bar includes a changeable middle section of different materials to study the effect of variation in material of the mid-section on temperature gradient along the bar. Insulation has been provided along the length of the bar to prevent convective and radioactive heat loss and to obtain more accurate result comparable with the theoretical result.

Project Objectives

To show however heat conducts linearly on a solid bar of uniform dimension and materials
• To show however totally different material involved will have an effect on linear heat transfer
• To show however you'll calculate the experimental thermal physical phenomenon of the        fabric in an exceedingly solid bar
• to show however thermal past facilitate to provide a decent thermal affiliation

Project Implementation Method

 Specimen:

• Brass

• Aluminum

• Cast iron

• Copper

Measuring the conductivity of specimens using two different methods

• The absolute method

• The comparative cut-bar method the electric heater and thermocouples connect to sockets on the Heat Transfer Experiments Based Unit, from which we can record the temperatures as the heat conducts along the bar. Insulation around the bar reduces heat loss by convection and radiation, so that the results should be close to the theory for simple linear conduction only. (Heat loss can also be simply estimated using a pre-determined Heat Conduction Chart of different metals)

Benefits of the Project

One of four optional experiments for the Heat Transfer Experiments Base unit

 • Fits quickly and easily onto the Heat Transfer Experiments Base Unit needs no tools

 • Shows the principles of linear heat conduction along a rod of uniform diameter

• Clear schematic printed on the baseplate aids student understanding

• Allows the thermal conductivity of various materials to be measured

• Safe, low-voltage heater with over-temperature cut-out

Technical Details of Final Deliverable

Fourier’s Law of Heat Conduction makes it possible to calculate not only the temperatures and values ??of heat transfer and the temperature variations between solids, but also structures such as thermal conductivity of solids that control how heat and temperature are distributed within them. The validity of the rule will be verified by Experiment by placing inactive items on the device. Since the temperatures in the various areas within the solids which are enclosed compacted with a heat-resistant coat will be measured over time to measure the temperature required to determine the heat transfer of the solid. This value will then be used to calculate the thermal fluctuations of the material samples, the solid heat transfer as predicted by the Fourier Act will be compared with the known input voltages and the thermal conductivity waves. The Fourier’s Law of Heat Conduction Act can be used to accurately measure heat transfer rates and temperature distribution with a relative error. Introduction From the beginning of human history heat was considered to give us a sense of warmth, but it was not only in the middle of the nineteenth century that the development of kinetic theory developed when we had a physical understanding of the nature of heat. . It was not until the nineteenth century that French mathematician Joseph Fourier published his book The Théorie analytique de la chaleur (The Analytic Theory of Heat), which stated that the flow of heat between two adjacent molecules corresponds to their temperature differences. Heat transfer systems are developed on the basis of the energy transfer between the neighbors.
