Yeast cells are recovered from a fermentation broth using a tubular

Yeast cells are recovered from a fermentation broth using a tubular centrifuge. At a flow rate of 12 L/min, the centrifuge must be operated at a rotation s rate of 4000rpm to collect the cells. You are asked to predict operation under different conditions. a. What rotation rate must you operate at if the flow rate is increased to 20L/min ? b. If the length of the tubular portion of the centrifuge can be replaced, how much longer must the length be if the flow rate is increased to 20L/min ? c. What rotation rate must the unit in part a) operate at if the particle diameter is doubled
