1. a. Differentiate the advantages of centrifugal filtration and centrifugal decantation. b. The centrifugal separation of a biomass of 80 um sized cells of density 1.04 kg m -3 was carried out in tubular centrifuge having a diameter of 15 cm and rotating at 1200 rev/min. i) Calculate the residence time if the distance between the liquid surface and the axis of rotation was 0.8 cm, the liquid density and the liquid viscosity were 1.0 kh m3 and 0.013 g cm-15-1 respectively. ii) What would be the volumetric capacity of the centrifuge if its length was 40 cm iii) Calculate the factor iv) What will be the time required for centrifuging 1000 litres of broth
