A column test $($darcy$)$ has been conducted in a laboratory. The test has been conducted at a temperature of $15,5$ degres celcius, in a cylindrical column who's area is $0,001$m$^2$ and who's lenght is $20$cm$.$ A hydraulic difference of $0\mathrm{.}25$m is kept throughout the tube, from one extremity to the other. The volume of water passing through the column in $5$ minutes equalsa $75*10^-6$ m$^3.$

Determine the hydraulic conductivity and the permeability of the sample. $($HC in m$/$s and permeability in m$^2)$
