As shown in the figure, an exterior wall of a building has an average thermal conductivity of 0.32 Btu/h-ft-ºR and a thickness of L = 4 in. At steady state, the temperature of the wall decreases linearly from T₁ = 70°F on the inner surface to T₂ on the outer surface. The outside ambient air temperature is To = 35°F and the convective heat transfer coefficient is 5.1 Btu/h-ft2°R. Wall K=0.32 Btu/h ft. R T₁- h 5.1 Btu/h ft. R -1₂ Determine the temperature T₂ in °F, and the rate of heat transfer through the wall, in Btu/h per ft² of surface area.
