Abstract

This research investigated the effect of some engineering properties (length, width, thickness, size, aspect ratio, surface area, sphericity, roundness, mass, volume, true density, bulk mass, bulk volume, bulk density, porosity, angle of repose and coefficient of static friction) on cassava biomass in relation to industrial processes. The results revealed that as the biomass increases the size, sphericity, bulk mass, length, width, thickness, aspect ratio, surface area, mass, volume, true density, bulk density, bulk volume and porosity increases whereas roundness, angle of repose and coefficient of static friction decreases as the biomass increases. There is significant difference between the biomass and the size, bulk mass, width, surface area, mass, volume and bulk volume whereas there is no significant difference between the biomass and the roundness, sphericity, length, thickness, aspect ratio, true density, bulk density, aspect ratio, coefficient of static friction and porosity. Correlation is significant at the 0.05 and 0.01 levels (2-tailed). Effects of yield on selected physical properties of cassava tubers had been investigated. The information provided in this research will be useful for farmers, engineers and energy providers who may wish to increase their biomass production capacity. Also, in the design of cassava implements and machinery for automation and mechanization of cassava tubers into useful products through the knowledge of the physical properties.
