Use of gaseous centrifugal technology to enrich isotopes is desirable as power consumption is greatly reduced when compared to more conventional techniques such as diffusion plants since fewer cascade steps are required to reach similar degrees of separation.

In the decades before the widespread adoption of the rotary combine in the late seventies, several inventors had pioneered designs which relied more on centrifugal force for grain separation and less on gravity alone.

It might involve a simple centrifugal separation or washing or flitration or capture by some form of selective binding or it may even involve modifying the target e. g. epitope retrieval in immunological assays or cutting down the target into pieces e. g. in Mass Spectrometry.

His suggestion that the continents had been pulled apart by the centrifugal pseudoforce ( Polflucht ) of the Earth's rotation or by a small component of astronomical precession was rejected as calculations showed that the force was not sufficient.

The centrifugal force from the Earth's rotation would pull a person ( on the inner surface ) outwards if the person was traveling at the same velocity as the Earth's interior and was in contact with the ground on the interior, but even the maximum centrifugal force at the equator is only 1 / 300 of ordinary Earth gravity.

In the late 1870s, the centrifugal cream separator was introduced, marketed most successfully by Swedish engineer Carl Gustaf Patrik de Laval.

Wren was unconvinced, Hooke did not produce the claimed derivation although the others gave him time to do it, and Halley, who could derive the inverse-square law for the restricted circular case ( by substituting Kepler's relation into Huygens ' formula for the centrifugal force ) but failed to derive the relation generally, resolved to ask Newton.

Darwin's hypothesis was that a molten Moon had been spun from the Earth because of centrifugal forces, and this became the dominant academic explanation.

In 1946, Reginald Aldworth Daly of Harvard University challenged Darwin's explanation, adjusting it to postulate that the creation of the Moon was caused by an impact rather than centrifugal forces.

Other mechanisms that have been suggested at various times for the Moon's origin are that the Moon was spun off from the Earth's molten surface by centrifugal force, that it was formed elsewhere and subsequently, was captured by the Earth's gravitational field, or that the Moon formed at the same time and place as the Earth from the same accretion disk.

Newton says that this thought experiment demonstrates that the centrifugal forces arise only when the water is in rotation with respect to the absolute space ( represented here by the earth's reference frame, or better, the distant stars ); instead, when the bucket was rotating with respect to the water no centrifugal forces were produced, this indicating that the latter was still with respect to the absolute space.

Negative feedback was first implemented in the 16th Century with the invention of the centrifugal governor.

While the first practical centrifugal compressor was designed in 1899, centrifugal superchargers evolved during World War II with their use in aircraft, where they were frequently paired with their exhaust driven counterpart, the turbosupercharger.

( The first extra term is the Coriolis force, the second the centrifugal force, and the third the Euler force.

Turbochargers were first used in production aircraft engines such as the Napier Lioness in the 1920s, although they were less common than engine-driven centrifugal superchargers.

In a practical gas turbine, gases are first accelerated in either a centrifugal or axial compressor.

The action of this principle is exactly like that of the centrifugal governor of the steam engine, which checks and corrects any irregularities almost before they become evident ; and in like manner no unbalanced deficiency in the animal kingdom can ever reach any conspicuous magnitude, because it would make itself felt at the very first step, by rendering existence difficult and extinction almost sure soon to follow.

The first mechanical tachometers were based on measuring the centrifugal force, similar to the operation of a centrifugal governor.

* Norwegian engineer Ægidius Elling builds the first gas turbine to generate power, using a centrifugal compressor.

De Laval also made important contributions to the dairy industry, including the first centrifugal milk-cream separator and early milking machines, the first of which he patented in 1894.

In case of non-rigid rotors, the first order centrifugal distortion correction is given by

may be given as prime grounds ( i. e. " explanation of ") some phenomena, but we may later find upon critical examination that this phenomenon supposedly explained by centrifugal force is actually used to infer centrifugal force in the first place.

The first VSD was applied to centrifugal compressor chillers in the late 1970s and

The action of this principle is exactly like that of the centrifugal governor of the steam engine, which checks and corrects any irregularities almost before they become evident ; and in like manner no unbalanced deficiency in the animal kingdom can ever reach any conspicuous magnitude, because it would make itself felt at the very first step, by rendering existence difficult and extinction almost sure soon to follow.

Suggested in 1919, the centrifugal process was first successfully performed in 1934.

The most " earth like " of the interstellar settlements, with arable land and strong gravity ( likely centrifugal ), these were mankind's first permanent habitation outside of Earth.

The first two terms are well-known classical energies, the first being the attractive Newtonian gravitational potential energy and the second corresponding to the repulsive " centrifugal " potential energy ; however, the third term is an attractive energy unique to general relativity.

i. e., when the two attractive forces — Newtonian gravity ( first term ) and the attraction unique to general relativity ( third term ) — are exactly balanced by the repulsive centrifugal force ( second term ).

Extractor -- centrifugal extractor of the laundry-type with a perforated basket, approximately 11 inches deep by 17 inches in diameter, with an operating speed of approximately 1,500 r.p.m..

* Ensuring ride comfort by absorbing vibration and minimizing centrifugal forces when the train runs on curves at high speed.

At some small angular rate of rotation, however, an element of surface water can achieve lower potential energy by moving outward under the influence of the centrifugal force.

The shoe ( s ) are held inwards by springs until centrifugal force overcomes the spring tension and the shoe ( s ) make contact with the bell, driving the output.

They believe that the star, dubbed the " Champagne Supernova " by University of Oklahoma astronomer David R. Branch, may have been spinning so fast that centrifugal force allowed it to exceed the limit.

Milestones among feedback, or " closed-loop " automatic control devices, include the temperature regulator of a furnace attributed to Drebbel, circa 1620, and the centrifugal flyball governor used for regulating the speed of steam engines by James Watt in 1788.

Although control systems of various types date back to antiquity, a more formal analysis of the field began with a dynamics analysis of the centrifugal governor, conducted by the physicist James Clerk Maxwell in 1868 entitled On Governors.

The oblate spheroid shape reflects, following Clairaut's theorem, the balance between containment by gravitational attraction and dispersal by centrifugal force.

The Coriolis force overcompensates the centrifugal force by exactly the required amount to provide the necessary centripetal force to achieve circular motion.

The term is again the centrifugal force, a force component induced by the rotating frame of reference.

A reactive centrifugal force is applied to the track by the cars.

From a qualitative standpoint, the path can be approximated by an arc of a circle for a limited time, and for the limited time a particular radius of curvature applies, the centrifugal and Euler forces can be analyzed on the basis of circular motion with that radius.

In contrast, in frames accelerating with respect to the fixed stars, an important case being frames rotating relative to the fixed stars, the laws of motion did not hold in their simplest form, but had to be supplemented by the addition of fictitious forces, for example, the Coriolis force and the centrifugal force.

If the spheres only appear to rotate ( that is, we are watching stationary spheres from a rotating frame ), the zero tension in the string is accounted for by observing that the centripetal force is supplied by the centrifugal and Coriolis forces in combination, so no tension is needed.

Within the church, William Lamont argues, the Elizabethan millennial views of John Foxe became sidelined, with Puritans adopting instead the " centrifugal " views of Brightman, while the Laudians replaced the " centripetal " attitude of Foxe to the ' Christian Emperor ' by the national and episcopal Church closer to home, with its royal head, as leading the Protestant world iure divino ( by divine right ).

A turbopump can comprise one of two types of pumps: centrifugal pump, where the pumping is done by throwing fluid outward at high speed ; or axial flow pump, where alternating rotating and static blades progressively raise the pressure of a fluid.
