Question 1: A steel pile with a diameter of D = 0.80 * / 100 m and a length of 23 m is planned to be driven into the soilprofile shown in the below figure. As a result of standard penetration test (SPT) performed at the construction site, soil profile and penetration numbers (SPT-N) are presented in Boring Log-1. The ground water table is located at a depth of 12 m. a .

Not all the components will always be present. Larger systems may have additional components, such as heat-exchangers in the fuel system for cooling, air pumps and methanol condensers in the CO2 outlet pipe. Note that the electrode connections are shown at the edge for simplicity; normally, the current will be taken off the whole face of the electrode, as in Figure 1.8, Chapter 1. Q2/ A soil sample is collected from field with a volume of 200 cm ?. The mass of soil at natural is determined to be 400g. Then, the soil is saturated with water and reweighted. The mass of saturated soil is 425g. After that, the soil sample is placed in oven at 105C for 1 hour to reach 380g then at a furnace at 550 C for 2 hours then it is reweighted to be 341 g. The data results are given bellow from the lab for the soil contaminant in the aqueous and soil phase. 0.1 0.2 0.3 0.4 0.5 Aqueous (mg/L) Solid (mg/Kg) 1.2 2.4 3.6 4.8 6 Calculate : Porosity, gravimetric water content, saturation ratio, dry bulk density, the partition coefficient Kd , fraction of organic carbon (foc), the partition coefficient between contaminant and organic koc, and fraction associated with solid fs
