Abstract:
In 2022, a comprehensive research study was conducted at the Department of Agricultural Engineering, IARI, New Delhi, India. The primary focus of this study was to investigate essential physical properties related to the MH-421 variety of green gram seeds. These properties included size, sphericity, test weight, bulk density, true density, coefficient of static friction, and angle of repose. The green gram seeds were characterized by specific measurements: they had an average length of 5.08 mm, a breadth of 4.06 mm, a thickness of 3.99 mm, and a geometric mean diameter of 4.35 mm. The sphericity of these seeds was calculated to be 86%. Mean bulk density and true density were determined with values of 0.86 g/cc and 1.38 g/cc, respectively. The angle of repose, a crucial parameter, was measured at an average of 23.94°. Notably, the coefficient of static friction exhibited variations when tested against different materials: 0.50 (aluminum), 0.45 (mild steel), 0.47 (galvanized iron), and 0.60 (plywood). Furthermore, the average thousand-grain weight for the selected variety of green gram seeds was found to be 46.18 g.
