Panicle accelerator

As in the case of Stokesian panicles, the contribution of panicle acceleration to the drag has been neglected. Clearly, (4.37) is on shaky ground from a theoretical point of view. Its application should be tested experimentally, but a rigorous validation has never been carried out. In nondimensional form. (4.37) can be written as follows ... [Pg.110]

Benchlop charged panicle accelerators are commercially available for the generation of neutrons. A typi-... [Pg.919]

A particle and a mixture introduced, confined, and rotated within a circular enclosure accelerates as it moves from a neutral center toward the maximum diameter (inner periphery) of the enclosure. Thus, if a mixture is introduced to the center of a 24-inch (61-cemiineler) diameter solid-bowl centrifuge rotating at 1500 rpm. the panicle will be caused to move at a speed of 32.2 feel (9 8 meters) per second at the center. At the maximum diameter, the particle will have a terminal velociiy of 766.8 x 32.2 feet per second, or 24.690 feet (7525 meters) per second. Essentially, the separaiion occurs at 766 8 x g. [Pg.315]

This wave-particle duality applies also to matter. Electrons, protons, neutrons, and other material panicles have been found to have properties which we usually correlate with wave motion. For example, a beam of electrons can be diffracted in the same way as a beam of X-rays. The wavelength associated with an electron depends upon the speed with which it is traveling. For electrons which have been accelerated by a potential drop of 40,000 volts, the wavelength is 0.06 A. [Pg.672]

As noted above. Stokes law is derived for the steady-state resistance to the motion of a particle. Why should it apply to the Brownian motion in which the panicle is continually accelerated The explanation is that the acceleration is always very small so that at each... [Pg.34]

Gravity separations depend essentially on rite density differences of rite gas, solid, or liquids present in the mix. The particle size of the dispersed phase and the properties of die continuous phase are also factors with rite separation motivated by die acceleration of gravity. The simplest representation of this involves rite assumption of a rigid spherical panicle dispersed in a fluid with rite terminal or free-settling velocity represented by... [Pg.128]

When a force F, such as a gravitational force, is applied to a particle in solution, the particle is accelerated. As its velocity increases, the particle experiences more and more retardation due to friction. For low velocities, the frictional force is given by /, where u is the velocity and /is the frictional coefficient. When the velocity gets high enough, the frictional force becomes equal to the applied force and the panicle moves with a constant velocity... [Pg.959]
