Experimental Determination of Thermal Conductivities of Cast Iron and Copper using Linear Heat Conduction Principle

Abstract

This research work deals with the determination of thermal conductivities of aluminum, cast iron and copper using linear heat conduction principle. The experiment was carried out within a distance of  holes 15mm for copper and 12mm for aluminum and cast iron drilled on the plastic rod  enable the sample material fit in perfectly between the heat region and the cold region. From the analysis, the results show that the thermal conductivity of copper, aluminum and cast iron is 289.023W/m. K,133.983W/make and 55.046W/make respectively. Comparing the results obtained with previous experiment, the thermal conductivity values obtained from the sample fall within the general range for materials.
