The emissivity of galvanized steel sheet, a common roofing material, is ε = 0.13 at temperatures around 300 K, while its absorptivity for solar irradiation is αS = 0.65. Find the temperature of a roof constructed of the material on a day when GS = 750 W/m 2 , T[infinity] = 16°C, and h = 7 W/m 2 · K. Assume the bottom surface of the steel is insulated.
