Yeast cells are to be separated from a fermentation broth. Assume that the cells are spherical with diameter 5 µm and density 1.06 g cm-3. The viscosity of the culture broth is 1.36 x 10-3 N s m-2. At the temperature of separation, the density of the suspending fluid is 0.997 g cm-3. 500 litres broth must be treated every hour. Specify Σ for a suitably-sized disc-stack centrifuge
