Author(s): HN Rokade, PA Borkar and TB Surpam
Abstract: Physical properties were determined. Different physical properties, viz. size in terms of length, width and thickness were determined for fifty grains as well as sphericity, bulk density, porosity, true density, and an angle of repose were also determined for black gram at the moisture content of 10.18 (± 0.089), 11.46 (± 0.446), 12.22 (± 0.131) and 13.86 (± 0.071) (w b) respectively. Major axis L (mm) 04.36 (00.116), 04.57 (00.084) 04.74 (00.175) and 05.03 (00.060) and minor axis T (mm) 03.49(00.10), 03.67(00.10), 03.78 (00.09) and 03.83 (00.07) respectively. Geometric mean diameter (mm) 03.92(00.070), 04.10(00.060), 04.23(00.072), 04.35(00.051) and Sphericity (%) 00.90(00.020), 00.89(00.016), 00.89(00.022) and 00.86(00.010) respectively. Test weight [1000 grain wt. (g)] was 49.05(00.485), 49.87(00.075) 50.72(00.188) and 51.83(00.946). Bulk density (g/cc) 00.78(00.002), 00.77(00.001), 00.77(00.001) and 00.76(00.002) and true density (g/cc) 01.33(00.019), 01.32(00.020) 01.31(00.027) and 01.30(00.024) respectively. Porosity (%) 41.56 (00.852), 41.59(00.994), 41.29(01.139) and 40.95(01.172). Angle of repose (degrees) 27.70 (00.675), 28.44 (00.726) 28.66 (00.500) and 29.20 (00.421) Terminal velocity (m/s) 10.32(00.052), 10.47(00.051) 10.64(00.062) and 10.70 (00.421).
