Unifоrm vоlumetric heаt generаtiоn of 20 kW/m3 is tаking place within a long rod of 50 mm diameter with a thermal conductivity of 0.15 W/m·K. The rod is positioned co-axially within a larger circular, thin-walled tube of 60 mm diameter whose surface temperature is maintained at 500ºC. The annular region between the rod and the tube is evacuated, and their surfaces are diffuse and gray, with an emissivity of 0.2. (a) Calculate the temperature at the surface of the rod. (16 points) (b) Calculate the temperature at the center of the rod. (4 points)
