The operations of numerous common rotating mechanical systems are most easily conceptualized in terms of centrifugal force. For example: A centrifugal governor regulates the speed of an engine by using spinning masses that move radially, adjusting the throttle, as the engine changes speed. In the reference frame of the spinning masses ...
A centrifuge is a device that uses centrifugal force to subject a specimen to a specified constant force - for example, to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g. cream from milk) or liquids from solids. It works by ...
For example, the Sorvall #SS-34 rotor has a maximum radius of 10.8 cm, so the formula becomes =, which can further simplify to =. [6] When compared to gravity, the particle force is called the 'Relative Centrifugal Force' (RCF).
the centrifugal force, the Coriolis force, and, for non-uniformly rotating reference frames, the Euler force. Scientists in a rotating box can measure the rotation speed and axis of rotation by measuring these fictitious forces. For example, Léon Foucault was able to show the Coriolis force that results from Earth's rotation using the Foucault ...
The magnitude of centrifugal force being used must also be considered. Centrifugal force aids with dewatering but hinders the transport of cake in the dry beach. Hence, a tradeoff exists between cake conveyance and cake dewatering. A balance between the two is necessary for setting the pool and G-force for a particular application. [5]
Diagram of a gas centrifuge with countercurrent flow, used for separating isotopes of uranium. A gas centrifuge is a device that performs isotope separation of gases. A centrifuge relies on the principles of centrifugal force accelerating molecules so that particles of different masses are physically separated in a gradient along the radius of a rotating container.
G factor (ratio of centrifugal force to gravitational force) is in the range of 2000-3000. Examples of common gearbox ratio used are 20, 40, 116, 130, and 140:1. Dewatering sludge is more effectively processed using centrifuges with larger pool volumes. Pool depth (radial height of liquid) can be changed in most centrifuges.
The centrifugal force essentially serves as an applied capillary pressure for small test plugs, often composed of brine and oil. During the centrifugation process, a given amount of brine is expelled from the plug at certain centrifugal rates of rotation.
