2.) A plane wall is made of brick with a thermal conductivity of 1.5 W/(m⸳K). The wall is 20 cm thick and has a surface area of 10 m2 . One side of the wall is exposed to outside air blowing against the wall resulting in a heat transfer coefficient of 20 W/(m2 ⸳K). The other side is exposed to an air-conditioned room with a convective heat transfer coefficient of 5 W/(m2 ⸳K). a. What are the thermal resistances corresponding to conduction through the wall and convection at each wall surface? b. For every 1 o C of temperature difference between the outside and inside air, how much additional cooling power is required from the air conditioner?
