The composition and phase diagrams of a typical soil mass is shown in Figure Q1. If the specific gravity of the soil solids is 2.7, show from first principle that the bulk unit weight of the soil is given by: Ybulk = 26.5(1 + w) (1 + e)

A soil sample has a natural water content of 20.6% and it is known to have Gs of 2.6.In order to determine the density of a soil, a portion of soil weighing 222 g is put in a 500 cm³ container. It is filled with 377 cm³ of water to fill the container. a) Determine the moist unit weight of the soil in kN/m³. b) Determine the dry unit weight of the soil in kN/m³.c) Determine the void ratio

The moist weight of 5.56 x 103 m³ of a soil is 120.3 x 10³ kN. The moisture content and the specific gravity of the soil solids are determined in the laboratory to be 10 % and 2.6, respectively. Calculate the following: a. Moist unit weight. (Enter your answer to three significant figures.) Y = kN/m³ b. Dry unit weight. (Enter your answer to three significant figures.) Yd= kN/m³ c. Void ratio. (Enter your answer to three significant figures.) e
