Transient heat transfer method was used for the determination of parameters among which is density, specific heat and thermal diffusivity at constant moisture level of 71.7±0.76% (wet basis). Both the density and specific heat of the sample increased with increase in temperature to maximum levels after which further increase led to a reduction of these parameters values and were independent of sample’s geometry. The thermal diffusivity and computed thermal conductivity were found to increase with increase in temperature. Conclusively, these engineering properties were correlated with temperature using polynomials of the third order empirical equation. ER -
