A centrifuge with 70 cm diameter and 35 cm height is being operated at 1000 rpm. it is employed to clarify a slurry consists of solid particles (with specific gravity of 1.5) in a liquid of specific gravity 1.2, and viscosity 4 cp at 150 m3/h. if a 5 cm thick liquid layer is formed inside the bowl and having the following particle size distribution, compute what % of particles will be separated in this centrifuge.
