In: Misr Journal of Agricultural Engineering 2016.v.33(4)Summary: This study was conducted to investigate physical. mechanical and aerodynamic properties of Jatropha seeds cultivated in Egypt. The properties were determined at moisture content of Jatropha seed 8.25 (%, d. b.). The results showed that the mean values of the %ages by weight of seed parts to whole seed was 60.84 and 39.16 % for kernels and husks. respectively. The results also include the following properties; length, width, thickness, arithmetic and geometric mean diameter, sphericity. aspect ratio. mass of individual seed, thousand seed mass, true density, bulk density, porosity, surface area, specific surface area and projected area; their averages were found to be 17.28 mm, 11.06 mm, 8.11 mm, 12.15 mm, 11.57 mm, 67.05 %, 64.18 %, 0.598 g, 551.1 g, 0.713 glcm3 , 0.425 g/cm3 , 39.89%, 421.6 mm2 , 3.08 cm2/cm3 and 154.4 mm 2 , respectively. The mean value of angle of repose was 0.466 rad. For the coefficient of static friction; the stainless steel surface had the lowest value (0.196) while; the Plexi-glass surface had the highest value (0.403). The highest values of the rupture force. deformation ratio. hardness and the energy needed for rupture force were 101.3 N. 0.13, 105. 17 N/mm and 61. 7 Nmm while; The lowest values were 57.0 N. 0.05. 99.17 N/mm and 19.1 Nmm. respectively. The average values of terminal velocity and coefficient of drag were 14.27 m/s and 0.30. respectively. Also; the average value of Reynolds number was 10898 therefore; the pattern of air flow is turbulent.
