Particle size - Wikipedia

Particle size is a notion introduced for comparing dimensions of solid particles (), liquid particles (), or gaseous particles ().The notion of particle size applies to particles in colloids, in ecology, in granular material (whether airborne or not), and to particles that form a granular material (see also grain size

Neutrino - Wikipedia

History Pauli' proposal. The neutrino was postulated first by Wolfgang Pauli in 1930 to explain how beta decay could conserve energy, momentum, and angular momentum ().In contrast to Niels Bohr, who proposed a statistical version of the conservation laws to explain the observed continuous energy spectra in beta decay, Pauli hypothesized an undetected particle that he called a "neutron", using ...

Sieve Analysis, Particle Size Analysis - AboutCivil.Org

Particle Size Passing the Sieves: In Sieve analysis the notation Dxx refers to the size D, in mm, for which xx percent of the sample by weight passes a sieve mesh with an opening equal to D. The D10 size, sometimes called the effective grain size, is the grain diameter for which 10% of the sample (by weight) is finer.

Porosity - Wikipedia

Porosity of surface soil typically decreases as particle size increases. This is due to soil aggregate formation in finer textured surface soils when subject to soil biological processes. Aggregation involves particulate adhesion and higher resistance to compaction. Typical bulk density of sandy soil is between 1.5 and 1.7 g/cm 3. This ...

Ventilation in Buildings | CDC

By definition, a High Efficiency Particulate Air (HEPA) filter is at least 99.97% efficient at capturing particles 0.3 µm in size. This 0.3 µm particle approximates the most penetrating particle size (MPPS) through the filter. HEPA filters are even more efficient at capturing particles larger and smaller than the MPPS. Thus, HEPA filters are ...

Particle filter - Wikipedia

The objective of a particle filter is to estimate the posterior density of the state variables given the observation variables. The particle filter is designed for a hidden Markov Model, where the system consists of both hidden and observable variables. The observable variables (observation process) are related to the hidden variables (state ...

Dynamic Light Scattering Particle Size Distribution Analysis

Particle size can be determined by measuring the random changes in the intensity of light scattered from a suspension or solution. This technique is commonly known as dynamic light scattering (DLS). In general, the technique is best used for submicron particles and can be used to measure particle with sizes less than a nanometer.

Wave - Wikipedia

Refraction is the phenomenon of a wave changing its speed. Mathematically, this means that the size of the phase velocity changes. Typically, refraction occurs when a wave passes from one medium into another. The amount by which a wave is refracted by a material is given by the refractive index of the material.

Grain size - Wikipedia

Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials . This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.

Filtration Efficiency - an overview | ScienceDirect Topics

This is in alignment with the literature finding of a minimum filtration efficiency at a certain particle size in micron scale when the pore size to particle size ratio becomes large (O’Melia and Ali, 1978; Yao et al., 1971), confirming the results of this study. With the PBE model, the actual size selectivity of the filters are derived.
