A12-m long and 5-m high wall is constructed of two layers of 1-cm thick sheetrock (k 0.17 w/m °c) spaced 12 cm by wood studs (k 0.11 w/m-°c) whose cross section is 12 cm x 5 cm. the studs are placed vertically 60 cm apart, and the space between them is filled with fiberglass insulation (k = 0.032 wm_°c). the house is maintained at 20°c and the ambient temperature outside is-5°c. taking the heat transfer coefficients at the inner and outer surfaces of the house to be 8.3 and 35 w/m^2 c, respectively. determine a) the thermal resistance of the wall considering a representative section of it b) the rate of heat transfer through the wall.
