$2-$ A constant pressure filtration test results are shown below. After collection of $0\mathrm{.}01m^3$

of the filtrate the thickness of the cake is $4\mathrm{.}4cm.$ The surface area of the filter is $450$

$c{m}^2.$ The pressure drop is $150$kPa. Determine the specific resistance of the cake and

the equivalent resistance of the filter medium.

The cake is assumed incompressible.
