Determination of engineering properties of pearl millet (Bajra)

Abstract

The engineering properties of Pearl millet (Pennisetum glaucum) were determined at moisture content of 9.066 ± 0.078 % (wb). The mean values obtained for length, width and thickness were 3.522, 2.590 and 2.100 mm, respectively. The average value for geometric mean diameter, sphericity, weight of thousand grains, bulk density, true density and porosity were 2.511 mm, 0.676, 9.896 g, 852.644 kg.m-3, 1267.236 kg.m-3 and 32.716 % respectively. The angle of repose mean value was 38. The co-efficient of static friction on three types of structural material was found to be ranging from 0.378 (steel sheet), 0.422, (galvanised iron sheet) and 0.426 (card board).
