14.2-1. Constant-Pressure Filtration and Filtration Constants. Data for the filtration of CaCO3 slurry in water at 298.2 K (25°C) are reported as follows (R1, R2, M1) at a constant pressure (-Δp) of 46.2 kN/m2 (6.70 psia). The area of the plate-and-frame press was 0.0439 m2 (0.473 ft2) and the slurry concentration was 23.47 kg solid/m3 filtrate. Calculate the constants α and Rm. Data are given as t = time in s and V = volume of filtrate collected in m3.

Filtration Constants for Constant-Pressure Filtration. Data for constant-pressure filtration at 194.4 kN/m2 are reported for the same slurry and press as in Problem 14.2-1 as follows, where t is in s and V in m3: V × 10^3 t V × 10^3 t V × 10^3 t 0.5 6.3 2.5 51.7 4.5 134.0 1.0 14.0 3.0 69.0 5.0 160.0 1.5 24.2 3.5 88.8 2.0 37.0 4.0 110.0

$an-equation-used-to-evaluate-vacuum-filtration-is-qfracdelta-p-a2alphaleftv-r-wa-r_fright-where-q-do$

An equation used to evaluate vacuum filtration is $$Q=\frac{\Delta p A^{2}}{\alpha\left(V R w+A R_{f}\right)}$$ Where $Q \doteq L^{3} / T$ is the filtrate volume flow rate, $\Delta p \doteq F / L^{2}$ the vacuum pressure differential, $A \doteq L^{2}$ the filter area, $\alpha$ the filtrate "viscosity," $V \doteq L^{3}$ the filtrate volume, $R \doteq L / F$ the sludge specific resistance, $w \doteq F / L^{3}$ the weight of dry sludge per unit volume of filtrate, and $R_{f}$ the specific resistance of the filter medium. What are the dimensions of $R_{f}$ and and $\alpha ?$
