A sample of moist soil having a wet mass of 1.0 kg and a volume of 0.64 liter (6.4 ´ 10-4 m3) was dried in the oven and found to have a dry mass of 0.8 kg. Assuming a typical value of particle density of 2650 kg/m3, calculate the bulk density rb, porosity f, mass water content qg, volumetric water content qv, and air-filled porosity fa.

: A wet soil sample with a water content of 15% and percentage air voids of 20% was oven dried. If the soil sample is cylindrical in dimension with length as 100 mm and diameter as 50 mm, then how much mass of water is present in the soil? Also calculate the mass of soil. Assume specific gravity of soil is 2.69 Interpret your answer and conclude how water content influences the unit weight of soil.
