Question

Consider a 4-m high, 6-m wide and 0.3-m-thick brick wall whose thermal conductivity is $k = 0.8$ W/m·K. On a certain day, the temperatures of the inner and outer surfaces of the wall are measured to be $14^\circ C$ and $6^\circ C$, respectively. Find the thermal resistance of the wall. Determine the rate of heat loss through the wall on that day. Ans: 1.563 x 10-2, 512 W
