The walls of a room are 4 m high and 6 m wide. The wall consists of several materials as shown in the picture on the side. The part of the wall that is in the room is the one that has a layer of foam. The temperature in the room is 22°C, while the outdoor temperature is -4°C. Foam Plaster Assume that heat transfer occurs in one dimension only 1.5 cm and ignores the effects of radiation. Calculate the rate of heat transfer that occurs through the wall. The values of the coefficients involved are: Brick 30 cm W kfoam = 0.026".K m kplaster= 0.22. K $1.5 cm m kbrick = 0.72".K m W hindoor= 10- 18 cm houtdoor= 20,.K m2
