This particle size D10 is called Effective Size. If the value of uniformity coefficient is equal to the 1, that means D60 and D10 are the same particles. In that case the whole soil mass consists of only one grain size and graph of such case will be something like this. A vertical straight line. Such soils are definitely poorly graded and are ...

PDF Calculating and Plotting Size Distributions

The size modulus is a measure of how coarse the size distribution is, and the distribution modulus is a measure of how broad the size distribution is. Size modulus for a size distribution can be determined from a graph by extrapolating the straight-line portion up to 100% passing and finding the corresponding size value. The distribution ...

The Rosin-Rammler particle size distribution - ScienceDirect

Sep 01, 1980 · If the value of n is 1.0, x9o = 2.3xo In conclusion, it should be reiterated that although the Rosin-Rammler particle size distribution is a useful tool in describing shredded refuse, it is nothing more than an empirical equation which seems to fit the particle size distribution curve.
