A viscous solution containing particles with a density P = 1461 kg/m3 is to be clarified by a centrifugal separator. The solution density is 801 kg/m3 and its viscosity is 100 cp (0.1 Pa.s). The centrifuge has a bowl with r2 = 0.02225 m and r1 = 0.00716 m, and height b is 0.197 m. Calculate the critical particle diameter in the exit liquid stream if N = 23000 rev/min and the flow rate q = 0.002832 m3 /h
