Determination of Some Physical Properties of Nutmeg (Myristica fragrans) Seeds

Some physical properties of nutmeg (Myristica fragrans) seeds were determined at moisture content of 81.85% wet basis. The mean length, width and thickness of the seeds were 23.09, 21.20 and 18.64 mm, respectively. The average value for geometric mean diameter, sphericity, mass, surface area, volume, true density, bulk density and porosity were 20.88 mm, 90.45%, 5.270 g, 1388.85 mm2, 5860.00 mm3, 1199.18 kg/m3, 686.60 kg/m3 and 41.83%, respectively. The coefficient of static friction on four types of structural surface was found to be ranging from 0.206 (galvanized steel sheet) to 0.376 (rubber).
