Q 2. An experimental home insulation material helps to maintain a 60ft×40ft, single floor building's temperature, T2, at 22∘C with the assistance of a 1200 W air conditioner on a hot day where the ambient temperature, T1, is 35∘C. The home builder, unfamiliar with the metric system, specifies the height of the wall as 8ft, the distance between the centers of the wall studs as 16′′ and the wall thickness as 3.5′′. What is the thermal conductivity ( k-value) of this mystery insulation for the described scenario? HINT: The wall studs are standard, spruce 2×4 's with a 1.5 " ×3.5′′ cross-section and 8 ft length. Also, the heat transfer per section of insulated wall can be determined by dividing the total rate of heat transfer by the ratio of the building perimeter normalized with respect to the width of a single wall section (16∗).
