    • centrifugal Flying off or proceeding from a center; radiating or sent outward from a focus or central point: opposed to centripetal: as, centrifugal force or energy; centrifugal rays or spokes.
    • centrifugal Operating by radial action; producing effects by centrifugal force: as, a centrifugal filter, pump, or machine. (See phrases below.)

    • n centrifugal plural Sugars made in a centrifugal machine.
    • n centrifugal A drum in a centrifugal machine.
    • centrifugal Obtained (as milk or cream) by the *centrifugal method (which see).
    • n centrifugal A trade-name for any machine which employs centrifugal force to separate a liquid from a solid or to separate liquids of different specific gravities. In all, the liquids to be separated, or the liquids and solids, are placed in a vessel which is rotated at a high speed, the lighter liquids being thrown off to the sides of the vessel where they overflow and escape, or the liquids mingled with the solids being thrown outward through perforations in the sides of the vessel. The cream-separator is an example of the first and the laundry extractor an example of the second method. Machines which are essentially centrifugal are given different names in different trades, as centrifugal extractor (or simply extractor), honey-extractor, cream-separator, centrifugal drier, hydro-extractor, Babcock's centrifugal or milk-tester. See drier,*extractor, *honey-extractor, *milk-tester (with cut), and separator.

    • adj Centrifugal sen-trif′ū-gal relating to the force directed towards the centre of curvature constantly required to keep a body moving in a curve instead of in its natural straight line:
    • adj Centrifugal sen-trif′ū-gal (bot.) applied to an inflorescence when the development proceeds from the apex towards the base of the axis or leaf, as opposed to centripetal, when it is from the base upwards towards the apex

In poetry:

Of the interminable sisters,
Of the ceaseless cotillions of sisters,
Of the centripetal and centrifugal sisters, the elder and younger
sisters,
The beautiful sister we know dances on with the rest.
With her ample back towards every beholder,
