Some physical properties of African nutmeg (Monodora myristica)

Physical and some frictional properties of African nutmeg (Monodora myristica), a wild perennial edible plant, were investigated at a moisture content level of 4.93% dry basis. Measured values for sphericity, unit volume, average geometric diameter, unit mass, true density, bulk density, surface and pro- jected areas were 0.74 0.064, 1008 mm 3 169, 12.42 mm 0.70, 0.89 g 0.14, 830, 488 kg m -3 , 483 and 1216 mm 2 , respectively. The average values for coefficient of static friction on four test surfaces ranged from 0.502 (for galvanized iron sheet) to 0.702 (for rubber). Thus, the technical data obtained from this study may be useful in the design of process machines.
