Abstract:
Some physical properties of cotton seeds (Gossypium hirsutum L) were determined at the moisture content of 7.8 per cent (w.b.). The size, sphericity, surface area, geometric mean diameter, test weight of grains, true density, bulk density and porosity were mm, 0.6216, 131.154 mm² , 6.46 mm, 112.216 g, 1.1561 g/ml , 0.6477 g/ml , and 36.106 %, respectively. The mechanical properties of the cottonseeds viz., angle of repose, coefficient of static friction using different surfaces were also determined and the values were 45.33^o, 1.104 (mild steel), 1.2912 (play wood), 1.038 (glass) and 1.11 (Perspex), 1.018 (Asbestos), respectively. The terminal velocity of the grains was 10.84 m/s.
