Coleus tubers, physical properties, thermal properties, moisture contentAbstract
Some important physical and thermal properties of coleus tubers were determined in the moisture range of 466.62 to 21.52% (d.b). Selected physical properties, namely weight, size; bulk density, particle density and porosity increased with increase in moisture content. Specific heat and thermal conductivity increased with increase in moisture content, while thermal diffusivity recorded a decreasing trend with increase in moisture content.
