Physical and mechanical properties such as bulk density, true density, angle of internal friction, porosity, and static coefficient of friction are necessary for the design of transport, processing and storage structures for barley seeds. The physical and mechanical properties were evaluated as a function of moisture content of grain varying from 10% to 14%. In this moisture range, as the bulk density decreased linearly from 647.34 to 623.00 kg/cubic m, true density increased linearly from 984.00 to 1,013.67 kg/cubic m. The porosity and angle of internal friction increased with the increase in the grain moisture content up to 38.5% and 22.5%, respectively, at 14% moisture content. The static coefficient of friction increased from 0.877 to 0.993, from 0.773 to 0.920, and from 0.560 to 0.713 for concrete (BS 30), galvanized steel and wood surfaces, respectively.
