Please answer my homework problem. show all work so I can understand. thank you!
The following data were obtained from sand-cone experiment where a volume of a certain soil is replaced with a sand in order to find the density of the soil. Density of sand used in test = 1.3 g/cc Wt. Of soil excavated from the pit = 925 g Wt. of sand filling the pit = 675 g Water content of natural soil = 15% Specific gravity of Solid = 2.7 a) Determine the wet density of the soil in g/cc. b) Determine the dry density of the soil in g/cc. c) What is the porosity of the soil?
8 The following are results of a field unit weight determination test using sand cone method: Volume of hole = 0.0019 m3 Mass of moist soil from hole = 3.24 kg Water content = 12.01% Max. dry unit weight from a laboratory compaction test = 19.70 kN/m3 Determine the relative compaction, in percent. Round off to two decimal places. Hint: Relative compaction = Field dry unit weight / Max dry unit weight (lab)
The following are results of a field unit weight determination test using sand cone method: Volume of hole = 0.0019 m3 Mass of moist soil from hole = 3.48 kg Water content = 12.43% Max. dry unit weight from a laboratory compaction test = 19.56 kN/m3 Determine the relative compaction, in percent. Hint: Relative compaction = Field dry unit weight / Max dry unit weight (lab)

3. The following are the results of a field unit weight determination test performed on the soil by means of the sand cone method. Calibrated dry density of Ottawa sand = 1570 kg/m³ Calibrated mass of Ottawa sand to fill the cone = 0.545 kg Mass of jar + cone + sand (before use) = 7.59 kg Mass of jar + cone + sand (after use) = 4.78 kg Mass of moist soil dug from hole = 3.007 kg Water content of moist soil = 10.2% Max dry unit weight = 19 kN/m³ a. Determine the moist unit weight of compacted soil in kN/m³. b. Find the dry unit weight in kN/m³. c. Compute the relative compaction in the field.

Following are the results of a field unit-weight determination test performed on the same soil by means of the sand cone method: -Calibrated dry unit weight of Ottawa sand = 15.4019 kn/m3 -Calibrated weight of Ottawa sand to fill the cone = 5.3496 N -Weightof jar + cone + sand (before use) = 74.451 N -Weightof jar + cone + sand (after use) = 46.886 N -Weight of moist soil from hole = 29.509 N -Moisture content of moist soil = 10.21% DETERMINE AND SHOW COMPLETE SOLUTION 1. Dry density of compaction in the field in kg/cu.m.
Figure Q1(b)(i) shows the result of a Shelby tube sample of field moist soilcontaining weight wet and dry soil as 7.951 kg and 6.795 kg, respectively.It is estimated that the Gs of soil is considered as 2.7. With the aid of a soildiagram, compute the values of W, γd, γm, n and S.
2. A sensitive volcanic clay soil was tested in the laboratory and found to have the following properties: . p=1.28 Mg/m³ e = 9.0 S = 95% Ps= 2.75 Mg/m³ W = 311% In rechecking the above values, one was found to be inconsistent with the rest. Find the inconsistent value and report it correctly. Show all your computations and phase diagrams.
An undisturbed soil sample was taken from the middle of a clay layer (i.e., 1.5 m below GL), as shown in figure. The water table was at the top of clay layer. Laboratory test results are as follows: Natural water content of clay : 25% Precdonsilidation pressure of clay : 60 kPa Compression index of clay : 0.50 Recompression index of clay : 0.05 Specific gravity of clay : 2.70 Bulk unit weight of sand : 17 kN/m3 A compacted fill of 2.5 m height with unit weight of 20 kN/m3 is placed at the ground level. 1 m Sand GWT 1 m Clay Hard stratum Assuming unit weight of water as 10 kN/m³, the ultimate consolidation settlemnet (expressed in mm) of the clay layer is
A soil sample has a bulk unit weight of 17.9 kN/m^3 at a water content of 16.9%. Use Gs=2.57 Determine the porosity. Answer in TWO(2) decimal places. Numerical values only. Don't indicate units here, just on the submitted solution.
