Microbial cell recovery is carried out in a continuous disc-stack centrifuge. The centrifuge is operated at 5000 rpm for separation of baker's yeast. At a feed rate of 60 1/min, 50% of the cells are recovered. At constant speed, solid recovery is inversely proportional to flow rate. What operating speed is required to recover 90% of cells if the flow rate in the centrifuge is maintained at 601/min?
