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 = 0:12 W/ m-C) on the outside. Assume the inside
room air is 20 C with convection coefficient of 10W/ m
2
– C and the
outside air at =10 C with convection coefficient of 20 W/ m
2
– C.
Also, determine the rate of heat transfer through the wall in Watts. Assume
one-dimensional heat flow through the wall thickness.
