2.The owner of the house in number 1 is thinking that heat of 1.2 kW coming from the wall is too high, he then decides to add a layer of 5 cm of expanded polystyrene in order to insulate the building. The rest of the wall is still be made of bricks. Bricks have a conductivity of 0.8 W/m/K and are 15 cm wide. Expanded polystyrene has a thermal conductivity of 0.04W/m/K The wall is 6 m long per 3 m high. He measures now 35 degrees on the outside surface and 22 degrees on the surface of the wall inside. Calculate the heat transferred. D
