1.	A viscous solution contains particles with a density is to be clarified by centrifugation. The solution density is and its viscosity is 80 cp. The centrifuge has a bowl with and 3 1200 / p = kg m³ = 850 / kg m²r m = 0.02 1 r = 0.01 m and height b=0.25 m. Calculate the critical particle diameter of the largest particles in the exit stream if N=15000 rpm and flow rate q=0.002 m³ /hr?
A.	2.9 m
B.	2.66 m
C.	3.15 m
D.	2.57 m
Answer» E.
