Consider a 4 m high, 6 m wide and 0.17 m thick wall whose thermal conductivity is k = 0.8 W/m.oC. On a certain day, the temperatures of the inner and the outer medium close to the wall are measured to be 14oC and 6oC, respectively. Both inner and outer surfaces are subjected to convection heat transfer. Assume that the convection heat transfer coefficient is the same for the two surfaces h = 5 W/m2 ∙ °C.

1. Draw the network of the thermal resistances for the conductive and convective heat transfer through the wall.

2. Evaluate the thermal resistances for the conductive and convective heat transfer through the wall as well as the total thermal resistance.

3. Determine the rate of heat loss through the wall on that day.
