Question
6. A batch centrifugal filter having a bowl diameter of 750 mm and a bowl height of 450 mm is used to filter a suspension having the following properties: Temperature: liquid, water Porosity of cake Final thickness of cake Specific cake resistance Filter medium resistance Speed of centrifuge Concentration of solids in feed Density of dry solid in cake = 25°C 0.435 = 150 mm = 9.5 x 10¹⁰ ft/lb 2.6 x 10¹⁰ per ft = 2,000 rpm = 60 g/li 2000 kg/m³ The final cake is washed with water under such conditions that the radius of the inner surface of the liquid is 200 mm. Assuming that the rate of flow of wash water equals the final rate of flow of filtrate, the rate of washing in m³/hr ? a. 0.60 b. 0.40 c. 0.75 d. 0.85
