A dilute slurry contains small solid food particles having a diameter of 30 pm which are to be removed by centrifuging. The particle density is 1300 kg/m and the solution density is 900 kg/m To be separated from the liquid, the particles must reach the bowl wall before they come to the end of the bowl. The viscosity of the liquid is 1.15 x 10-3 Pa.s. A centrifuge at 3000 rev/min is to be used. liquid discharge The bowl dimensions are: b= 100 mm, r1= 10.00 mm, and r2= 40.0 mm. liquid surfac a. Calculate the angular velocity (W, rad/s). particle trajectory bowl wall 41 feedi feed flow b. Calculate the maximum volumetric flow rate (q, m/s) that will still remove the particles. 18 C. Plot how the minimum captured particle diameter (dp.min) changes with w (assume q is constant and equal to the value from part b): w (rad/s): 125 250 500 1200 2500 Plot dp,min VS. q (assume w is constant and equal to part a value) for: q (m/s): 3.2E-05 1.1E-04 8.4E-04 3.6E-03 7.0E-03 d. Calculate the critical particle diameter of the largest particles in the exit stream if the flow rate changes to q= 30 m3/hr
