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

The pore water has $0\mathrm{.}00075MAlC{l}_3.$ Temperature $24C$

Determine:

i$)$ The double layer thickness.

ii$)$ The surface potential.

iii$)$ Potential 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 $30\frac{V}{m}?$

v$)$ Determine $k_{eo}$ for this soil. Assume $36\%$ porosity.

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