The wall of a house is made from a layer of wood 3cm thick and a layer of wool which is 5.3 cm thick. The layer of wood faces outside and the layer of wool faces inside. The thermal conductivity of wood is 0.08W/mK and the thermal conductivity of wool is 0.02W/mK. The temperature outside the house is 0oC and the temperature inside the house is 19.8 oC. What is the temperature (in oC) at the contact surface between the wool and the wooden layers?

A layer of cork 6 inch thick is used as layer of thermal insulation in a flat wall. The temperature of the cold side is 40 oF and that of the warm side is 180 oF. The thermal conductivity of the cork at 32 oF is 0.021 Btu/ft-h-oF and that at 200 oF is 0.032. The area of the wall is 25 ft. Estimate the rate of heat transfer through the wall. Answer: 182 Btu/hr

A 20 m thick saturated clay layer is normally consolidated. At mid-depth in this layer, the void ratio (e) is 1.110, the coefficient of compressibility (av) is 5.74 x103 cm2=N. Recall that w = 9.81 kN/m3. a) Assuming that a 122 cm lowering of the ground water table (GWT) occurs in the soil overlying the clay layer, what settlement will occur in the soil overlying the clay layer because of the ultimate primary consolidation of the clay layer? Express your...
