An electronic package in the shape of a sphere with an outer diameter of 100 mm is placed in a large laboratory room. The surface emissivity of the package can assume three different values (0.2, 0.25, and 0.3). The walls of the room are maintained at a constant temperature of 77 K. The electronics in this package can only operate in the surface temperature range of 40°C ≤ T_s ≤ 85°C. Determine the range of power dissipation (W) for the electronic package over this temperature range for the three surface emissivity values (ε). Plot the results in terms of W (W) vs. T_s(°C) for the three different values of emissivity over a surface temperature range of 40 to 85°C with temperature increments of 5°C (total of 10 data points for each ε value). Provide a computer generated graph for the display of your results and tabulate the data used for the graph. Comment on the results obtained.
