Filtration tests were carried out with a plate-and-frame filter press at 20°C under the following conditions: ρ_s = 2,710 kg/m³, filter area 0.37 m², filtrate m = 0.001 N-s/m², and c_F = 10.037 kg/m³.

The filter pump was controlled manually until the pressure became constant at 150,000 N/m², which occurred at approximately V = 0.3 m³, t = 3,686 s. Make a plot of the data, t/V versus V, and determine the specific cake resistance, a, and the medium resistance, R_m.
