Extracted text: Q3// A rotary filter is required for the filtration of a slurry to produce 10 m' in 3500 s, the pressure difference is a constant at 70 kN/m´ and 20% of the drum is submerged in the slurry. A sample was tested on a laboratory filter of area 0.023 m² to which it give filtrate at a constant rate of 0.0125 m/s. The pressure difference across the test filter increased from 14 kN/m? after 300 s to 28 kN/m² after 900 s. What are suitable diameter for the rotary filter. Assuming that the resistance of the cloth used is the same that on the test filter.
