1.1 The average effective overburden pressure on a 10 mts – thick layer in the field is 136 kN/m2 and the average void ratio is 0.98. If a uniform surcharge of 200 kN/m2 is applied on the ground surface, determine the consolidation settlement for the following cases, Cc = 0.35, Cs = 0.08.
a)Preconsolidation pressure, σ'p = 350 kN / m2 b) b)Preconsolidation pressure, σ'p = 150 kN / m2

1.2 For case b) of the previous exercise determine, a) What is the void ratio at the end of 100% of consolidation. b) If Cv = 1.5 mm2 / min, how long will it take to settle the first 100 mm? Take the two-way drain for the clay layer.

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
