Effect of centrifugation conditions. A tubular centrifuge that rotates at 4,000 rpm when fed with a yeast broth at a rate

of 12 L/min, manages to recover 60% of solids.

You are asked to estimate:

a) The speed at which the centrifuge must rotate to obtain 95%

recovery.

b) The flow that can be fed to the centrifuge when it rotates at 4,000 rpm

and a 95% recovery is desired.

Ans. a) 4,845 rpm and b) 8.18 L/min
