Understanding & Interpreting Particle Size Distribution Calculations

Rank–size distribution is the distribution of size by rank, in decreasing order of size. For example, if a data set consists of items of sizes 5, 100, 5, and 8, the rank-size distribution is 100, 8, 5, 5 (ranks 1 through 4). This is also known as the rank–frequency distribution, when the source data are from a … Visa mer In the case of city populations, the resulting distribution in a country, a region, or the world will be characterized by its largest city, with other cities decreasing in size respective to it, initially at a rapid rate and then more … Visa mer The rank-size rule (or law) describes the remarkable regularity in many phenomena, including the distribution of city sizes, the sizes of businesses, … Visa mer • Pareto principle • Long tail Visa mer • Media related to Rank-size distribution at Wikimedia Commons Visa mer A rank-size (or rank–frequency) distribution is often segmented into ranges. This is frequently done somewhat arbitrarily or due to external factors, particularly for market segmentation, but can also be due to distinct behavior as rank varies. Visa mer While Zipf's law works well in many cases, it tends to not fit the largest cities in many countries; one type of deviation is known as the Visa mer • Brakman, S.; Garretsen, H.; Van Marrewijk, C.; Van Den Berg, M.

The most general way is the following. Let P (X) be the probability that random number generated according to your distribution is less than X. You start with generating uniform random X between zero and one. After that you find Y such that P (Y) = X and output Y.

For relatively spherical particles it is close to 2*Rg, for less spherical particles can get larger, may be up to 4* Rg. It is important to guess large enough number, but not too large. To help, you can try using the button “Guess maximum”.

WebbIn this approach, the particle size probability density function (PDF) is the image of the nucleation rate at the nuclei time of birth. The functional dependence of the PDF with the particle size is eventually obtained by inverting ̅= ̅(𝑡,𝜏). This size distribution function is usually called Johnson and Mehl (JM) PDF [3].
