Organic soils are typically characterized by high void ratio, low specific gravity, and high compressibility. Following are the results of a consolidation test on a sample of organic soil obtained from southwest Florida. Pressure, o' (kN/m²) Change In dial reading, AH (mm) 0.284 0.150 6. 12 24 0.315 48 0.564 100 0.823 2.25 5.34 200 400 Given that the initial height of the specimen= 20.6 mm, mass of dry specimen = 12 g, area of specimen : 31.67 cm², and Gs = 2.49, d. Plot the e-log o' curve. Determine the pre-consolidation pressure. е. f. Calculate the compression index, Cc.

A clean sandstone core sample with diameter of 3.8 cm and length of 5.6 cm is saturated with a brine. The core was desaturated in several steps, and the resistance was measured at each saturation. The results are as follows: Water Saturation (Fraction) Resistance (kS) 1.000 1.302 0.900 1.695 0.800 2.283 0.730 2.878 0.640 3.775 0.560 5.637 0.480 7.838 0.375 13.175 0.350 17.050 0.300 26 Brine resistivity= 0.74 2m Archie coefficient 1.03 Cementation factor= 2.2147 (1) Estimate the rock porosity. (2) Determine the saturation exponent. (3) Estimate the amount of oil and brine (in cc) in the core sample when resistivity index is 5. All steps of the calculations should be shown.
