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-ft
2
– F. The outside
air temperature is 10 F with a heat transfer coefficient of h = 6 Btu/h-ft
2
–
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.
