WebCoefficient of uniformity, Cu and the coefficient of curvature, Cc, are the parameters based on D-size to define grading. Coefficient of uniformity, and coefficient of curvature, Where D. Cu = D 60 / D 10. Cc= (D 30) 2 /D 10 ×D 60. Where, D 10 — Particle diameter at which 10% of the soil mass is finer than this size. WebThe relationship between porosity, median size, and sorting coefficients has been investigated by studying synthetic sands with lognormal size distributions and various median sizes and sorting coefficients. Poorly sorted sands are considerably less porous than well sorted ones, and porosities show an inverse linear relationship to sorting ...

Poorly sorted sands show a wide range of grain diameters, well-sorted sands have similar sized grains. As sand grains are transported by wind, water or whatever process, the grain size tends to decrease, roundness increases, and sorting increases. WebFiner-grained materials (e.g., silt and clay) tend to have greater porosity—some as high as 70%—than coarser materials (e.g., gravel). Primary porosity tends to be higher in well-sorted sediments compared to poorly sorted sediments, where there is a range of smaller particles to fill the spaces made by the larger particles. fly from gatwick to jersey
