Problem $2$: Soil type: $30\%$ Illite, $50\%$ Kaolinite, $15\%$ Smectite.

The pore water has $0\mathrm{.}00075$ MAlCl $.$ Temperature $24C$

Determine:

i$)$ The double layer thickness.

ii$)$ The surfece potential.

iii$)$ Potental at a distance $5$ angstroms.

iv$)$ Assuming that the slipping plane is at a distance of $5$ angstroms, what will be EO

velocity in the pores under an electric gradient of $30\frac{V}{m}?$

Determine ke for this soif. Assume $36\%$ porosity,

vi$)$ Determine the EO fiov rate through a $3m2m$ cross$-$section.
