Problem $2$

Total $($moist$)$ unit weight of a split$-$spoon sample of silty clay was measured in lab to be $20k\frac{N}{m^3}.$ Moisture content of the sample was measured to be $17$ percent. Assuming specific gravity of the soil solid to be $2\mathrm{.}67,$ calculate the following:

$($a$)$ Dry unit weight

$($b$)$ Void ratio

$($c$)$ Porosity

$($d$)$ Degree of saturation

Problem $3$

For the data given in Problem $2,$ determine the weight of water in $kN,$ to be added per cubic meter $(m^3)$ of soil to increase the degree of saturation to:

$($a$)92$ percent

$($b$)100$ percent
