Aslurry containing 100 kg of fine particles per m' of water is filtered under constant pressure of 200 kn min a plate and frame press. in a lab scale experiment performed under constant pressure difference of 200 kn m produced flow of water through a filter cake of 1 cm volume was 0.03 cm's! the cake is incompressible and has a voidage of e=0.45. calculate: (1) the specific resistance of the cake for the lab scale experiment, r(m2); [10 marks] (ii) the thickness of the cake in a plate and frame press, l(m) formed after t=1000s of filtration (10 marks] additional information: • the resistance of the filter medium may be neglected, the viscosity of water is p =1 mns m? the density of the particles is p = 3000 kg m
