The roof of an automobile can be thought of as a flat plate with insulated bottom surface. Solar radiation of 1000 W / m2 comes to the ceiling surface of this car in open air. The radiation spreading ratio of the surface is 0.8 and the absorption ratio is 0.7, and the heat transfer coefficient between the ceiling and the outdoor air is 12 W / m2K. Since the ceiling surface temperature is 45 ° C in continuous mode, what is the outdoor temperature?
