The pressure drop information from three lab filtrations conducted at constant pressure are listed as follows. Determine the cake specific resistance, a, as a function of pressure drop. The data will be used to size a rotary drum with the diameter of 0.5 m, to filter 2700 m3/hr slurry. Calculate the length of the drum. Rotary Drum: Submerged fraction = 30%. Rotation speed =1 rpm. Expected pressure drop = 150 kPa. Lab Test Conditions: Filter area: 500 cm². Mass of solid per unit of filtrate = 25 kg/m3. Cake moisture content = 50%. Viscosity and density of water are 1e-3 kg/m.s and 1000 kg/m3.
