Question details

A house has a composite wall of wood, fiberglass insu- lation, and plaster board, as indicated in the sketch. On a cold winter day, the convection heat transfer coeffi- cients are h 60 W/m2 K and h 30 W/m2 K. The total wall surface area is 350 m2
Glass fiber blanket (28 kg/m2), k Plaster board, kp Plywood siding, k Inside Outside hor To, -15°C 10 mm 100 mm 20 mm (a) Determine a symbolic expression for the total thermal resistance of the wall, including inside and outside convection effects for the prescribed conditions. (b) Determine the total rate of heat loss through the wall.
