Q.1: A filter has an area of 2 m' and operates at a constant pressure drop of 250 kPa. The following results were obtained during a test with an incompressible cake: Volume of filtrate collected 280 430 540 680 800 (liter) Time (min) 10 20 30 45 60 Calculate: (a) The time required to collect 1200 liter of filtrate at a constant pressure drop of 400 kPa with the same feed slurry. (b) The rate of passage of filtrate at the end of the filtration in part (a)
