1) Calculate the mass of water needed to saturate 1m3 volume of soil that has a water content of 4% and a void ratio = 67%. Express answer in kg.

Urgent need

The wet unit weight of a soil is 20 kN/m3 and its water content is 12%. Calculate its dry unit weight in kN/m3. Input only the numerical value without the unit.

Question 2 A soil has a water content of 25 %, a void ratio of 0.7, and a specific gravity of solids of 2.7. (a) On the phase diagram shown below, choose the total volume to be equal to one, and fill up all other quantities. Use Kg for mass and m³ for volume. Volume (m³) V₁ Vy Vw Vs AIR WATER SOLIDS Phase Diagram Mass (Kg) Mw X Ms (b) Use the phase diagram to calculate the following quantities. (i) total density (ii) dry density (iii) degree of saturation (iv) saturated density (assume no volume change) M₁
