MOISTURE DEPENDENT PHYSICAL PROPERTIES OF AFRICAN OIL BEAN SEED

In this research, some of the physical properties of P. Macrophylla seed have been quantified. The physical properties showed variation with the mean value just like all biological materials. The dimension of the African oil bean seed was found to be relatively larger than other seeds. The average geometric, square and arithmetic means of the dimensions ranged from 55.7–56.76mm. The sphericity, roundness factor and roundness ratio were found to be very low (0.75, 0.23 and 0.19, respectively). The specific gravity (1.15) and density (1.04gcm^-3) were very close to that of water. The bulk density averaged 1.10gcm^-3, which is lower than that of most seeds. The angle of repose and coefficient of static friction were 17.20^0 and 0.31, respectively.
