Likely, particles are entrained in helical flows and are acted on, differentially, by gravity and sterics (size differences restrict movement around microstructures).
Why? Buoyancy is a function of gravity, and gravity, like size and time, is affected by rapid motion through space.
Physical properties such as specific gravity and grain-size distributions were obtained through specific gravity examination and grain-size distribution tests under ASTM D854-10 ASTMASTM D6913 procedures, respectively.
In these experiments, the adsorption of particles is most probably the dominant mechanism because of the low specific gravity and small particle size.
We demonstrate the ease of designing neutron transport systems using simple numeric tools, which are verified using Monte-Carlo simulations that allow taking into account effects of gravity and finite beam size.
The effects of droplet shape, the strength of gravity, droplet size, and meniscus curvature for the spontaneous motion of droplets and bubbles are investigated in detail.
Samples weighing 10 to 50 kg (22 to 110 pounds) are collected, crushed, and ground into a fine sand, and the various minerals are isolated on the basis of specific gravity, grain size, and magnetic properties.
Fragmental volcanic material becomes sorted in flight under the influence of gravity, particle size, and wind.
At three and a half hours, his "Albert Speer" makes considerable demands on our rumps, minds and political sensibilities, but, as Trevor Nunn directs the play in the National Theater's Lyttelton auditorium, you will surely be impressed by its size, gravity and willingness to ask difficult questions.
Machines have been developed to separate and clean seed, based on size, specific gravity, and surface characteristics.
