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
