6. A viscous solution containing particles with a density of particle, 1461 kg/mĀ³ is to be clarified by
centrifugation. The solution density is 801 kg/mĀ³ and its viscosity is 100 centipoise. The tubular
bowl centrifuge has a bowl with r2= 0.02225 m, rā = 0.00716 m, and height b=0.1970 m. Calculate
the critical particle diameter, Dpc, of the largest particles in the exit stream if rotational speed,
N=23000 RPM and flow rate q= 0.002832 mĀ³/h.
