For the basement wall shown in Figure P13–40, determine the temperature distribution and the heat transfer through the wall and soil. The wall is constructed of concrete (k = 1.0 Btu/h-ft-° F). The soil has an average thermal conductivity of k = 0.85 Btu/h-ft-° F. The inside air is maintained at 70 ° F with a convection coefficient h = 2.0 Btu/h-ft²-° F. The outside air temperature is 10 ° F with a heat transfer coefficient of h = 6 Btu/h-ft²-° F. Assume a reasonable distance from the wall of five feet that the horizontal component of heat transfer becomes negligible. Make sure this assumption is correct.
