Heat transfer

Heat transfer problem 2

A brick wall with a thermal conductivity of 0.6 has an area of and a thickness of 0.4 m. A surface window is built into the wall. The window allows a heat flow rate of 1.6 W per square meter of the surface at a temperature difference of 1 K. The difference between the indoor and outdoor temperature is 20 K. What is the heat flow rate through the wall with the window? How much heat is lost in one day?
