The outer surface of the grill hood shown in the figure below is at 47°C and the emissivity is 0.93. The heat transfer coefficient for convection between the hood and the surroundings at 27°C is 10 W/m2K. Determine the net rate of heat transfer between the grill hood and the surroundings by convection and radiation, in kW per m2 of surface area. (Hint: Watch “convection and radiation”)
