4. please answer correctly and show the solution

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.

Don't attempt wrong i will downvote.....A cylindrical soil sample, 7.3 cm in diameter and 16.8 cm in height, is tested in a constant-head permeability apparatus. A constant head of 75 cm is maintained during the test. After 1 minute of testing, a total of 945.7 gm of water was collected. The temperature was 20 oC. The void ratio of the soil was 0.43. Calculate the following: 1. The hydraulic gradient 2. The flow rate 3. The discharge velocity 4. The seepage force per unit volume 5. The coefficient of permeability

(detailed and clean solution please)  large soil sample obtained from a borrow pit has a wet mass of 26.50kg. the in – place volume occupied by the sample is 0.013m3. A small portion of the sample is used to determine the water content; the wet mass is 135g, and after drying in an oven, the mass is 117g. a. Determine the soil’s water content. b. Determine the soil wet and dry density for conditions at the borrow pit.

1. From the following data of a soil sample: Sample size 3.81 cm dia. x 7.62 cm ht. Wet weight = 1.668 N Oven-dry weight = 1.400 N Specific gravity = 2.70 Detemine the water content (%), dry unit weight (kN/m3), bulk unit weight (kN/m3), void ratio, and the degree of saturation (%).
