The walls of a house are constructed of an exterior sheathing, insulation, framingtimber, and drywall. The composite resistance of the materials is 4.15 m2-K/W. On a winter daywhen the outdoor temperature is -5oC, wind blows at 30 km/hr parallel to the 3 m high, 18 m longwall. If the convection coefficient on the interior side of the wall is 5 W/m2-K and the interiortemperature is 21oC, determine the rate of heat loss through the wall.
