ABSTRACT:
In hydrometer analysis for soil grain size distribution,
usually, the grains passing sieve No. 200 (, there are big differences between the values
of soil grain diameters smoothed by Excel-2007 in comparison and the
values measured by references. These differences generally decrease with
decreasing soil grain size diameters. The statistical treatments also divulge whether the hydrometer results are accurate or not. Furthermore, a general equation
has been derived to estimate values of K factor, which is used
for calculating the grain diameters in hydrometer analysis. The equation can be
applied for any specific gravity of soils and for wide range temperatures.
