In a filtration experiment, the slurry in water at 25 °C was filtered through a plate and frame filter system at a constant pressure (-AP) of 300 kpa. The filtration time and the obtained filtrate volume (m³) was recorded as shown in the following table: Time (s) V (m³) Time (s) V (m³) Time (s) V (m³) 10 1.05E-03 50 3.15E-03 90 4.51E-03 20 1.73E-03 60 3.53E-03 100 4.80E-03 30 2.27E-03 70 3.88E-03 110 5.08E-03 40 2.74E-03 80 4.21E-03 120 5.35E-03 The filter' total area was A 0.05 m2 and the slurry concentration was 20 kg/m³. a) Calculate the specific cake resistance a; b) Calculate the total resistance due to the filter medium Rm; c) Calculate the total resistance due to the filter cake Rc when 5 liters of filtrate was collected; d) If we keep the filtration process going, please predict the volume of the total filtrate collected at the filtration time t= 3 min.
