Particle Size Distribution Functions:

Distribution Functions: Since it is often not possible to obtain particle size data from d p = 0 to d p = ∞, it is desirable to use a function with a minimum number of free parameters to describe the particle size distribution. From such a function all moments can be calculated. If the function has 3 free parameters, for example, such as the ...

Particle size

Particle size is a notion introduced for comparing dimensions of solid particles ( flecks ), liquid particles ( droplets ), or gaseous particles ( bubbles ). 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 ).
