Comparison between sieve analysis & hydrometer with laser particle analyzer to determine particle size distribution

Determination of soil particle size distribution (PSD) by sieving, hydrometer as well as by laser particle analyzer suffers from inherent flaws, mainly due to the difficulty in defining the size of irregularly shaped particles. Therefore these methods yield only estimates of particle size distributi...

Coefficient of determination for the regression equations for the clay, silt, and sand fractions determined by the two methods were 0.702, 0.689, and 0.821, respectively.
