The walls of a house are 0.3 m thick and total surface area of the walls is 100 m2. Thermal conductivity (k) of the walls = 1 W/m2K. Temperature of outside air is 37°C and inside air is 27°C. Heat transfer coefficients inside and outside are 20 W/m2K and 10W/m2K. Calculate the inside and outside wall temperature, heat flux and heat transfer rate through the walls.
