The effect of variety and moisture content on
some engineering properties of five improved paddy rice
varieties was investigated within moisture content range
of 10% and 30% dry basis (d.b.).
Increase in moisture
content was found to increase the linear dimensions,
mass of 100 seeds, surface area, apparent volume, true
volume, arithmetic mean diameter, effective geometric
diameter, sphericity, angle of repose, porosity and static
coefficient of friction while bulk density and true density
decreased with increase in moisture content.
Static
coefficient of friction was found to increase as moisture
content increased from 0.34–0.46, 0.35–0.59, 0.36–0.46
and 0.34–0.45, respectively on plywood, galvanized
steel, mild steel and glass structural surfaces. The highest
static coefficient was found on galvanized steel. Angle of
repose was found to increase as moisture content
increases. The study concludes that variety and changes
in moisture content significantly (P
