Calculate the filtration constants. Using a filter-press with an area of 0.0929 m², Mc Millen and Webber report the following results for filtration at a constant pressure of 34.5 kPa of an aqueous suspension of 13.9% by weight of CaCO3, at 300K. The wet to dry cake mass ratio is 1.59. The density of the dry cake is 1017 kg/m3. The symbols correspond to W =kg of filtrate and t = time in S.

\begin{tabular}{|l|l|l|l|l|l|} \hline W & t & W & t & W & T \\ \hline 0.91 & 24 & 3.63 & 244 & 6.35 & 690 \\ \hline 1.81 & 71 & 4.54 & 372 & 7.26 & 888 \\ \hline 2.72 & 146 & 5.44 & 524 & 8.16 & 1188 \\ \hline \end{tabular}
