Question

a) A house walls that are 13 cm thick and have an average thermal conductivity three times that of cork. Assume there are no windows or doors. The walls’ surface area is 900000 cm² and their inside surface is at 18°C°C, while their outside surface is at 5°C°C. (Thermal conductivity of cork is 0.042 W/m°C)

(i) Calculate the rate of heat conduction through house walls?

(ii) How many 200W room heaters would be needed to balance the heat transfer due to conduction? (approximate number)
