Physical and mechanical properties of kenaf seed

This study was conducted to investigate some moisture-dependent physical and mechanical properties of kenaf seed (Hibiscus cannabinus L.). Selected physical and mechanical properties often are required for designing the planting, storage, and other processing equipment. The average length, width, th...
