Question #72116
The wall of a house consists of two 125 mm thick brick walls with an inner cavity. The inside wall has a 10 mm coating of plaster, and there is a cement rendering of 5 mm on the outside wall. In one room of the house the external wall is 4 m by 2.5 m, and contains a window of 1.8 m by 1.2 m of 1.5 mm thick glass. The heat transfer coefficients for the inside and outside surfaces of the wall and window are 8.5 and 31 W/m2K respectively. The thermal conductivities of brick, plaster, cement, and glass are 0.43, 0.14, 0.86, and 0.76 W/mK respectively. Assuming that the resistance of the air cavity is 0.16 m2K/W, neglectign all end effects, and neglecting radiation, calculate the proportion of the total heat transfer which is due to the heat loss through the window.
