Question

Determine the diameter and speed of a centrifuge required to reduce the total sedimentation time for the aggregates by a factor of 10, assuming you will use containers that are 20 cm high in the centrifuge.

Also assume that the center of rotaion is 3 cm from the tops of the container.

How much time must the same centrifuge be operated to also sediment all the singel cells?

For simplicity, assume a swinging bucket type of centrifuge, in which the axis of the cylindrical vessel is horizontal, hence parallel to the direction of sedimentation.
