Some engineering properties of mahogany seed and kernel were investigated and expressed as a function of moisture content. In the moisture ranges of 7.1–32% and 5.3–22% (d.b.), respectively, the seed and kernel length, width and thickness increased with increase in moisture content. One thousand seed and kernel weight increased linearly with moisture content. True density, bulk density, porosity and angle of repose of seed and kernel also increased with increase in moisture content. Static and kinetic coefficients of friction increased linearly with moisture content and varied with structural surfaces. Specific heat increased with increase in both moisture content and temperature. Regression equations were used to express the relationships existing between the engineering properties and seed and kernel moisture contents.
