For the composite wall of a house, shown in Figure P13–10, determine the temperatures at the inner and outer surfaces and at the interfaces. The wall is composed of 2.5 cm thick plaster wall (k = 0:20W/ m-° C) on the inside, a 9 cm thick layer of fiberglass insulation (k = 0:038W/ m-° C), and a 1.25 cm plywood layer ( k = 0:12W/ m-° C) on the outside. Assume the inside room air is 20 ° C with convection coefficient of 10W/m2-° C and the outside air at –10 ° C with convection coefficient of 20W/m2-° C. Also, determine the rate of heat transfer through the wall in Watts. Assume one-dimensional heat flow through the wall thickness.
