Ismor Fischer, 5/29/2012 5.2-6 . The tendency toward a normal distribution becomes stronger as the sample size n gets larger, despite the mild skew in the original population values. This is an empirical consequence of the Central Limit Theorem. For most such distributions, n …

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.

Cu = D60/D10. Cc – Coefficient of curvature. Cc = (D30)^2 /(D60)(D10). What is the use of this Cu and Cc? Cu is always greater than 1 (equal to 1 is possible only by theoretical).If Cu is closer to 1 ( ie. D60 and D10 sizes are close to each other, which means there are more no. of particles are in the same size range), the soil is considered as uniformly graded.

It is determined from the grain size distribution curve at the point where the curve crosses a horizontal line through the 10% passing value on the y axis. Other D sizes are found in a similar manner. The D50 size, called the median grain size, is the grain diameter for which half the sample (by weight) is smaller and half is larger. Two ...

D10, D50, or D90 is defined as the size value corresponding to cumulative size distribution at 10%, 50%, or 90%, which represents the size of particles below which 10%, 50%, or 90% of the sample lies. For example, size distribution data obtained form a laser diffraction measurement are plotted as a cumulative size distribution shown in Figure 2.

To find probabilities from a binomial distribution, one may either calculate them directly, use a binomial table, or use a computer. The number of sixes rolled by a single die in 20 rolls has a B(20,1/6) distribution. The probability of rolling more than 2 sixes in 20 rolls, P(X>2), is equal to 1 - P(X<2) = 1 - (P(X=0) + P(X=1) + P(X=2)). Using ...

The particle size of samples was determined using a laser diffraction instrument (Mastersizer 2000, Malvern, UK) equipped with the laser of 633 nm. The refractive index was set as 1.53, and the absorption parameter was set as 0.01. Particle size distribution was quantified as the relative volume of particles presented as size distribution curves.

In order to represent the size range (or particle size distribution), a frequency diagram or histogram is produced (see Figure 2 below). The x-axis records the particle size and the vertical height (y-axis) represents the amount of particles at that size (or in other words, the frequency of occurrence).
