A slurry is being filtered in a plate-and-frame filter press at a constant pressure drop of 10 psi under conditions where the resistance of the medium is negligible. The fluid viscosity is 2.0 lb/hr-ft; 5 lb of dry cake are collected for every ft³ of filtrate; and the cake is incompressible, with a specific cake resistance, α, of 8.34x 10¹⁰ ft/lb_m. What filter area is required to process 50 ft³ in one hour?
