Ahouse wall which is 2.75 m high and 10 m wide is made of 110 mm thick bricks on the outside, 10 mm thick plasterboard on the inside and 100 mm thick insulation in between. on the inside of house, air conditioning keeps the surface of the plasterboard at 18°c, whereas on the outside, the surface of the brick wall is exposed to still air at 0°c. determine the rate of heat loss through the wall notes thermal conductivities of materials in wall kplasterboard 0.17 wm-1k-1, kinsulation = 0.04 wm1k-1 and kbrick = 0.72 wm1k-1 properties of air at atmospheric pressure can be found in the back of the test script (page 9) hint: start by guessing the outside wall temperature in the range of 2-4°c
