2. Consider a vertical, single-pane window of width = height = 1 m. The interior surface is exposed to the air and walls of a room, which are each at 18°C. Under cold ambient conditions for which a thin layer of frost has formed on the inner surface, what is the heat loss through the window? As with most natural convection problems, radiation heat transfer may NOT be neglected. Use Trad = εσA, (T-T4) with & = 0.90. surr
