Particle size distribution: Classification of thermal spray powder materials as determined by various testing methods defining the particle sizes and quantities in a given sample
The fractions of the various soil separates in a soil sample, often expressed as mass percentages.
The percentage by weight, or by number, of each fraction into which a powder sample has been classified with respect to sieve number or microns.
The amount of the various soil separates (sand, silt, clay) in a soil sample, usually expressed as weight percentages.
A full representation of particle sizes in a solid specimen. The particle size distribution usually gives volume-based frequency of particles as a function of their size.
Refers to the number fraction or weight fraction of particles (in a fluid) falling into specified size ranges. For instance: Size Range# per Liter% by Number (PSD) 5-15 µm 1000 20 15-25 µm 3000 60 25-50 µm 1000 20
