[b] Continuous rotary vacuum drum filter with a cycle time of 55 s and an area of 60 m² is used to filter penicillin from fermentation broth at a rate of 18,000 L/h. This filtration unit operates under vacuum at 50 kPa. The broth forms a compressible cake and the specific cake resistance is represented by a = (4.37 × 10%) (AP)03 m/kg. The suspension has a viscosity of 8.93710 Pa.s and the cake solids (dry basis) per volume of-filtrate is 308.1-kg/m³. The-ratio-of the volume of liquid retained by the cake to the volume of filtrate is-0.10. With the objective of achieving 80% washing efficiency and retaining only 2% of the filtrate, calculate the filtration time per cycle and the washing time.
