Exploring certain physical and engineering attributes of okra seeds

Abstract

Understanding the physical and engineering attributes of a seed holds vital information essential for crafting its metering mechanism, processing, and storage system. A study was planned with objectives are study physical and engineering properties of okra seed. Based on the results salient finding are summarized as mean values the mean dimensions of the seed were determined to be 5.58 mm in length, 4.61 mm in width, and 4.18 mm in thickness. Geometric mean diameter for VNR-Deepika variety was found to be 4.79 mm. Sphericity and roundness found to be 85.2% and 82.85% respectively. The weight of 1000 okra seeds, along with their bulk density, true density, mean volume and average porosity were determined to be 57.06 g, 0.56 g cm-3, 1.12 g cm-3, 111.46 mm3 and 50.22% respectively. The laboratory observations revealed an average angle of repose under study of 25.97°. The coefficient of static friction was found to be 0.42.
