Sentences Containing 'centrifugal'
A centrifugal extractor—also known as a centrifugal contactor or annular centrifugal contactor—uses the rotation of the rotor inside a centrifuge to mix two immiscible liquids outside the rotor and to separate the liquids in the field of gravity inside the rotor.
A properly designed sucrose gradient will counteract the increasing centrifugal force so the particles move in close proportion to the time they have been in the centrifugal field.
A spacecraft enters orbit when it has enough horizontal velocity for its centripetal acceleration due to gravity to be less than or equal to the centrifugal acceleration due to the horizontal component of its velocity.
Annular centrifugal contactors are relatively low revolutions-per-minute (rpm), moderate gravity enhancing (100–2000 G) machines, and can therefore be powered by a direct drive, variable speed motor.
Annular centrifugal extractor design and development has been pursued by various Department of Energy laboratories for more than 40 years.
As described above, the "mix separation" configuration is the standard operation for centrifugal contactors used for liquid-liquid extraction processes.
At some point during this period he was given Frank Whittle's engine design using centrifugal compressors and returned a negative response; after pointing out minor errors in the calculations he stated that the centrifugal design was inefficient and its large frontal size would make it unsuitable for aircraft use.
Because the smoke rises in a cyclone-like fashion, the centrifugal force pushes the tar particles against the inner wall, where they will be collected through the air-jets.
By this point in time Whittle's centrifugal-compressor designs were fully operational, and plans were underway to start production of early models.
Centrifugal contactors are typical referred to by the diameter of their rotor.
Centrifugation is a process that uses centrifugal force to separate mixtures of particles of varying masses or densities suspended in a liquid.
D-Limonene is obtained commercially from citrus fruits through two primary methods: centrifugal separation or steam distillation.
Gravity is defined as the resultant of gravitation and the centrifugal force caused by the Earth's rotation.
HCFC-123 is used in large tonnage centrifugal chiller applications, and is the most efficient refrigerant currently in use in the marketplace for HVAC applications.
However, the centrifugal force of a spinning shell disperses the charge jet.
If samples are centrifuged long enough, the particles in the vessel will reach equilibrium wherein the particles accumulate specifically at a point in the vessel where their buoyant density is balanced with centrifugal force.
Initial design of the annular centrifugal contactor was done at Argonne National Laboratory through modification of a Savannah River Site paddle mixed design.
It includes an integrated swingarm, which houses a centrifugally controlled VDP-type continuously variable transmission using a rubber belt. At the rear of the swingarm, a centrifugal clutch connects the transmission to a simple integral gear-reduction unit.
Like chain drives, belt drives include a centrifugal clutch.
Many irrigating systems use centrifugal pumps to force water over long distances and to supply it in quantities sufficient for vast agricultural needs.
Most fans used in computers are of the axial-flow type; centrifugal and crossflow fans are sometimes used.
One simple explanation is that the outer air is under higher pressure than the inner air (because of centrifugal force).
Since 2010 graphics cards have been released with either axial fans or a centrifugal fan commonly known as a blower or squirrel cage fan.
The British Transport Commission installed a centrifugal pump to maintain the statutory minimum water level.
The centrifugal contactors thus acts as a mixer, centrifuge and pump.
The centrifugal governor was adopted by James Watt for use on a steam engine in 1788 after Watt’s partner Boulton saw one at a flour mill Boulton Watt were building.
The effectiveness of a centrifugal separation can be easily described as proportional to the product of the force exerted in multiples of gravity ("g") and the residence time in seconds or "g"-seconds.
The first tilting pad bearing in service was probably built under A.G.M. Michell's guidance by George Weymoth (Pty) Ltd, for a centrifugal pump at Cohuna on the Murray River, Victoria, Australia, in 1907, just two years after Michell had published and patented his three-dimensional solution to Reynold's equation.
The gland at the rotating shaft of a centrifugal pump may be packed in a similar way and graphite grease used to accommodate continuous operation.
The Interconnector works via four GE LM2500 gas turbines and a Thermodyn centrifugal compressor in its compressor station, which was built by Kværner John Brown (now called Aker Solutions).
The progress had been so swift that Whittle's argument that the centrifugal layout was mechanically superior than the axial designs appeared to be borne out.
The spring causes the dial to rotate back to its home position during which time its speed was maintained constant with a centrifugal governor.
The surplus water is best removed by centrifugal pumps, since sand and sticks which would clog the valves of an ordinary pump are passed along without difficulty by the rotating wheel.
The terminal has two GE 11MW Frame 3 and one GE 3.7MW Frame 1 gas turbines, connected to three centrifugal compressors.
These generally incorporate a type of centrifugal clutch to allow the engine to idle independently.
These high-quality pillars are homogeneous, the result of the seamless method of construction that utilizes centrifugal force.
This causes heavy macromolecules to migrate towards the bottom of the tube faster than lighter material. During centrifugation in the absence of sucrose, as particles move farther and farther from the center of rotation, they experience more and more centrifugal force (the further they move, the faster they move).
This way, a centrifugal extractor generates a continuous extraction from one liquid phase (fermentation broth) into another liquid phase (organic solvent).
Thus, a 5-inch centrifugal contactor is one having a 5-inch diameter rotor.
Typically for solvent extraction processes in stage-wise equipment such as the centrifugal contactor, you would have multiple contactors in series for extraction, scrubbing, and stripping (and perhaps others).
Usually centrifugal dryers are used, however oven are used for larger parts or loads.
Utility and industrial boilers commonly use multi-stage centrifugal pumps; however, other types are used.
When a ship or boat leans over to one side, from the action of waves or from the centrifugal force of a turn or under wind pressure or from amount of exposed topsides, it is said to 'heel'.
