Consider a glass window (k = 0.7 W/m K) with cross-sectional area of 2 m2 and thickness of 1 cm exposed to the air inside the room at 20oC on one side and cold outside air on the outside. If the convection coefficient, h, for the inside air is 10 W/m2 K, h for the outside air is 20 W/m2 K, and the inside window surface temperature is 15oC, find the heat loss through the window an
