You have a small shed with walls of plain carbon steel with atotal surface area of 20 m^2. The walls are 0.4 mm thick and arenot painted. You want to add air conditioning for summer use tomaintain an interior air temperature of 25 C when the external airtemperature is 35 C. The interior and exterior convective heattransfer coefficients are 1.3 W/(m^2-K) and 15 W/(m^2-K),respectively. To reduce the cost of air conditioning the shed, youadd a layer of cardboard having an R-value of 0.5 (SI Units) to allof the walls. What is the total heat loss rate (W) from the wallsof the shed?
