Exercise #$1$:

A soil sample has a void ratio of $0\mathrm{.}65,$ moisture content $=10\%$ and $G_s=2\mathrm{.}60.$ Determine

the following:

a$)$ Dry unit weight, moist unit weight $(K\frac{N}{m^3}).$

b$)$ Weight of water in $K\frac{N}{m^3}$ to be added for $80\%$ degree of saturation.

c$)$ Is it possible to reach a water content of $30\%$ without change the present void ratio.
