| | | | | | | | | | Centrifugal | n. A centrifugal machine. [ 1913 Webster ] | | Centrifugal | a. [ L. centrum center + fugere to flee. ] 1. Tending, or causing, to recede from the center. [ 1913 Webster ] 2. (Bot.) (a) Expanding first at the summit, and later at the base, as a flower cluster. (b) Having the radicle turned toward the sides of the fruit, as some embryos. [ 1913 Webster ]
Centrifugal force (Mech.), a force whose direction is from a center. [ 1913 Webster ]
☞ When a body moves in a circle with uniform velocity, a force must act on the body to keep it in the circle without change of velocity. The direction of this force is towards the center of the circle. If this force is applied by means of a string to the body, the string will be in a state of tension. To a person holding the other end of the string, this tension will appear to be directed toward the body as if the body had a tendency to move away from the center of the circle which it is describing. Hence this latter force is often called centrifugal force. The force which really acts on the body being directed towards the center of the circle is called centripetal force, and in some popular treatises the centripetal and centrifugal forces are described as opposing and balancing each other. But they are merely the different aspects of the same stress. Clerk Maxwell. [ 1913 Webster ]
Centrifugal impression (Physiol.), an impression (motor) sent from a nerve center outwards to a muscle or muscles by which motion is produced. --
Centrifugal machine, A machine for expelling water or other fluids from moist substances, or for separating liquids of different densities by centrifugal action; a whirling table. --
Centrifugal pump, a machine in which water or other fluid is lifted and discharged through a pipe by the energy imparted by a wheel or blades revolving in a fixed case. Some of the largest and most powerful pumps are of this kind. [ 1913 Webster ]
| | Centrifugal filter | . A filter, as for sugar, in which a cylinder with a porous or foraminous periphery is rapidly rotated so as to drive off liquid by centrifugal action. [ Webster 1913 Suppl. ] | | centrifugate | v. t. to drive out; to subject to the action of a centrifuge.
Syn. -- centrifuge. [ WordNet 1.5 ] | | centrifugation | n. the process of separating substances by the use of a centrifuge. [ WordNet 1.5 ] | | centrifuge | v. t. 1 to drive out; to subject to the action of a centrifuge.
Syn. -- centrifugate. [ WordNet 1.5 ] | | centrifuge | n. an apparatus having containers for liquids arrayed around a central pivot and rotated at a high speed, thus generating centrifugal force on the liquid, and separating substances (such as particles of solid or globules of an immiscible liquid) mixed together in suspension within the liquid. Suspensions which would settle only very slowly or not at all under gravity can be made to separate quickly in such a device. The containers for holding the liquid in a centrifuge are held in a metal frame called the head or trunnion. The solid material collected at teh bottom of the liquid container is called the pellet. A centrifuge designed to run at very high speeds and thus generate very high centrifugal force is called an ultracentrifuge.
Syn. -- extractor, separator. [ WordNet 1.5 +PJC ] | | Centrifugence | n. The property or quality of being centrifugal. R. W. Emerson. [ 1913 Webster ] | | centrifuge out | v. t. to separate (particles in a suspension) from a liquid by centrifugation.
Syn. -- centrifugate. [ PJC ] |
