[Example] Beer with a specific gravity of 1.042 and acry viscosity of 1.4 x 103 N-s/m² contains 1.5% solids, which have a density of 1160 kg/m³. It is clarified at a rate of 240 L/h in a bowl centrifuge, which has an operating volume of 0.09 m³ and a speed of 10,000 rev/min. The bowl has a radius of 5.5 cm and is fitted with a 4-cm outlet. Calculate the effect on feed rate of an increase in bowl speed to 15,000 rev/min and the minimum particle size that can be removed at the higher speed.
