Consider a wooden door with a glass window. The door is 5 cm thick and 0.75 m wide by 2 m tall. The window is 0.2 m square and 1 cm thick. The air on one side of the door has a temperature of 23°C and a heat transfer coefficient of 10 W/m2-K. The air on the other side of the door has a temperature of 7°C and a heat transfer coefficient of 5- W/m2-K. With and without using resistance analogies, determine the following:

a. The average temperature on each side of the door.

b. The heat transfer from one side of the door to the other.
