A soil sample has the following information available:

Specific gravity, GS$=29$

Wster Content, w $=16\mathrm{.}70\%$

Degree of saturation, $5$: $74\mathrm{.}0\%$

Then the void ratio of the specimen is

$2.$ A homogenous soil deposition is tested and summaried below:

$=$

$$

Saturated unit weight: yat $=126pcf$

Layer thickness: T$=17$ : ft

Groundwater table is at the groud surface.

Then the effective stress at the middle point of the layer is:

: $$ pas

$$

$3.$ Calculate the seepage force and seepage rate in the soil column below:

$H_1=2\mathrm{.}6m$

$H_2=4\mathrm{.}4m$

$h=0\mathrm{.}44m$

hydraulic conductivity of the sand $k=0\mathrm{.}14f\frac{t}{m}in$

area of the tank $A=2\mathrm{.}45,f{t}^2$

The rate of upward seepage of water is

The uplift seepage force per unit volume is:
