In an experiment to determine the thermal conductivity of a new metal alloy, a bar of the metal is completely surrounded by insulation and exposed to 705 W of constant heat energy at one end. The bar has a radius of 0.069 m and a length of 0.365 m. The entire set-up is place in a cold room and once the system has reached steady state conditions, the temperature at the hot end is measured to be 67.3°C and the temperature at the cold end is measured to be 10.5°C. What is the thermal conductivity (in W/m∙K) of the metal alloy [round your final answer to zero decimal places]?
