For a soil having a void ratio of 0.75 and percentage saturation of 85%, determine the porosity. (Answer must be round up to two decimal) Your answer

The coefficient of permeability of sand at a void ratio of 0.80 is 0.47 mm/s. Estimate the coefficient of permeability of this sand at a void ratio of 0.50.

Detailed solution please A clay has the following Atterberg limits: liquid limit = 60%, plastic limit = 40%, shrinkage limit = 25%. The clay shrinks from 15 cubic centimeters to 9.57 cubic centimeters when the moisture  content is decreased from the liquid limit to the shrinkage limit. a. What is the specific gravity? b. What is the plasticity index? c. What is the liquidity index if the water content is 52%? d. From a hydrometer analysis to determine particle sizes, it is found that 45 percent of the sample consists of particles smaller that 0.002 mm. From this information indicate the activity classification of the clay.

A clay sample has a plastic limit of 8% and liquid limit of 58%. Determine the plasticity index of the clay. Determine the liquidity index if the natural moisture content is 30%. What is measured by plastic limit and liquid limit?

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 (k2) 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 Qm 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.

Problem Set 2: 4. A sample of gray silty clay has a mass of 126 kg. Laboratory tests results give a moist density (p) of 2.05 g/cm³, a specific gravity of solids (G,) of 2.71, and a moisture content (w) of 15.7%. First determine all entries in the phase diagram. Then determine the void ratio (e), the porosity (n), the degree of saturation (S), the dry density (Pa), the dry unit weight (ya), and the moist unit weight (y). Draw the Phase diagram.

A soil specimen has a total volume of 70 cm3 and a total mass of 135.5g. After complete drying in an oven, the specimen has a mass of 122.0g. The Gs is 2.60. Determine the void ratio. Report your answer to three significant figures, and draw the full phase diagram.

A sample of gray silty clay has a mass of 126 kg. Laboratory tests results give a moist density(ρ) of 2.05 g/cm3, a specific gravity of solids (Gs) of 2.67, and a moisture content (w) of 14.7%.First determine all entries in the phase diagram. Then determine the void ratio (e), the porosity(n), the degree of saturation (S), the dry density (ρd), the dry unit weight (γd), and the moistunit weight (γ).
