Abstract

The study was conducted to investigate some physical properties of rue seed at various moisture levels. The average length, width and thickness were 0.712 mm, 0.475 mm and 0.442 mm, respectively, at moisture content of 6.12% (d.b). True density has increase from 1151.103 to 1182.326 kg m-3 when the moisture content increased from 6.12 to 21.47% (d.b). The angle of static friction increased from 31.54 to 38.52°, 26.80 to 32.87°, 10.05 to 22.60° and 12.91 to 16.69° for plywood, rubber, iron and galvanized, respectively, as the moisture content increases from 6.12 to 21.47% (d.b).
