A 4m thick clayey layer was initially water saturated with water content w = 34%, and in situ effective stress σzo’ = 31 kPa. Clearly state your assumptions to determine: a) The total settlement in this clay layer, if the final void ratio after consolidation is ef = 0.75. b) If OCR = 2.2, the construction of an embankment at this site induces 48.5 kPa additional load, what will be the total settlement at this site? Assuming Cc = 0.3 and Cr = 0.06. (c) What will be the settlement after 10 years of consolidation, assuming Cv = 3.2 × 10-7 cm2 /sec and double drainage condition.

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...

A closed, rigid tank is filled with water. Initially, the tank holds 0.6 lb of saturated vapor and 6.0 lb of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. Kinetic and potential energy effects can be ignored. Determine the volume of the tank, in ft3, the temperature at the final state, in °F, and the heat transfer, in Btu.

A thick steel slab (ρ= 7800 kg/m3, c= 480 J/kg·K, k= 50 W/m·K) is initially at 300°C and is cooled by water jets impinging on one of its surfaces. The temperature of the water is 25°C, and the jets maintain an extremely large, approximately uniform convection coefficient at the surface. Assuming that the surface is maintained at the temperature of the water throughout the cooling, how long will it take for the temperature to reach 50°C at a distance of...
