2. (a) 2 kg of dry sand is poured into a Eureka can, where it displaces 755 cm³ of water. Calculate the specific gravity of the sand particle. (b) When a 2 kg of the same sand is poured into a measuring cylinder of diameter 6 cm, it occupies a total volume of 1200 cm³. Calculate the void ratio of the sand and its unit weight in this state. (c) The measuring cylinder is carefully filled with water up to the level of the top of the sand, so that the total volume is still 1200 cm³. Calculate the unit weight of the saturated sand in this condition. (d) The side of the measuring cylinder is tapped gently several times, and the level of the sand surface settles to an indicated volume of 1130 cm³. Calculate the void ratio and the unit weight of the saturated sand in its dense state. Take the unit weight of water yw as 10 kN/m³, and the mass density of water as 1000 kg/m³.
