Now add a 6 in. thick concrete floor to the model of Figure P13-40 (as shown in Figure P13-41). Determine the temperature distribution and the heat transfer through the concrete and soil. Use the same properties as shown in Problem 13-40.
Figure P13-41,

Refer to Problem 13-40,
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-oF). The soil has an average thermal conductivity of k = 0.85 Btu/h-ft-8F. The inside air is maintained at 70 oF with a convection coefficient h = 2.0 Btu/h-ft2 -oF. The outside air temperature is 10 oF with a heat transfer coefficient of h = 6 Btu/h-ft2 -oF. 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.
