Answer to Question #127616 in General Chemistry for Asani

Question

A suspension of yeast cells is to be filtered at a constant filtration rate of 50 L/min. The suspension has a solid content of 70 kg/m³ of suspension and the yeast cells have a bulk density of 800 kg/m³. Laboratory tests indicate that the specific cake resistance is 40 m/kg and the viscosity of the filtrate is 2.9x10^-3 kg/m.s. The filter has an area of 0.1 m² and the medium offers negligible resistance. How long can the filtration rate be maintained before the pressure drop exceeds 1 N/m²? What volume of cake and filtrate are collected during this time? Note that ρ0 is expressed in mass of solids per volume of filtrate and NOT total volume of suspension. 

Answer 1

FILTRATION Removal of solid particles from a fluid by ... [Example] A suspension containing 225 g of carbonyl iron ... The specific cake resistance is 1011 ft/lb.
