Question

A dilute slurry contains small solid food particles having a diameter of 3 ´ 10-2 mm which are to be removed by centrifuging. The particle density is 1130 kg/m3 and the solution density is 980 kg/m3. The viscosity of the liquid is 1.2 × 10-3 Pa · s. A centrifuge at 4,000 rpm is to be used. The bowl dimensions are b = 100.1 mm, r1 = 6.0 mm, and r2 = 40.0 mm. Calculate the expected flow rate in m3/s just to remove these particles.
