Problem 2 Considering the heat transfer model shown in the accompanying figure, (A) determine the temperature distributions in the wall, the floor, and the soil and indicate the maximum and minimum temperatures and their locations, and (B) the heal loss from the floor (use path operation to find the total heat flow of concrete floor by selecting the 8ft long of left surface of the concrete wall) and the wall (use path operation to find the total heat flow of concrete wall by selecting the 8ft long of left surface of the concrete wall). As shown in the figure, assume that at about four feet away from the concrete wall and floor, the horizontal and the vertical components of the heat transfer in the soil become negligible. The thermal conductivity for soil is 0.31 Btu/hr⋅ft∘F and 0.61Btu/hr⋅ft⋅∘F for concrete. (units, use ft,∘F,Btu/hpur ) (note: remember to glue concrete and soil area together before meshing)
