Particle-size distribution - Wikipedia

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.

Particle Size Distribution - an overview | ScienceDirect ...

08-08-2011· The particle size distribution was measured using laser light diffraction particle size analyzer (LS 230, Coulter-Beckman, Germany). This allows measuring particle sizes from 0.04 μm to 2000 μm by combiniation of laser light scattering for measuring the coarse particles and polarization intensity differential scattering (PIDS) for measuring the finer particles.

Particle-size distribution – German Environmental …

The predominant particle-size fraction is name-giving, e.g. loamy-sand means a sandy soil containing a smaller loam fraction. The term 'loam' refers to a soil containing more or less equal fractions of sand, silt and clay. As one of the most conservative soil features the particle-size distribution is an especially useful and meaningful parameter.

Basic Principles of Particle Size Analysis - ATA Scientific

Most particle sizing techniques aim report particle size distributions on a two dimensional graph (ie. particle size on the x-axis and quantity of material on the y-axis). However, the difficulty with this is that there is only one shape that can be described by a single unique number, and that is the sphere.

Aerosol - Wikipedia

The normal distribution usually does not suitably describe particle size distributions in aerosols because of the skewness associated a long tail of larger particles. Also for a quantity that varies over a large range, as many aerosol sizes do, the width of the distribution implies negative particles sizes, clearly not physically realistic.
