We saw in Example 5.7 how a centrifuge can be used to separate cells from a liquid. To increase the speed at which objects can be separated from solution, it is useful to make the centrifuge’s speed as large as possible. If you want to design a centrifuge of diameter 68 cm to have a force of 9 X106 times the force of Earth’s gravity, what is the speed (in rev/s) of the outer edge of the centrifuge? Such a device is called an ultracentrifuge.
