The effects of temperature (50-80 degrees C) and moisture content 9.1-41.2% (wet basis) on the specific heat of ground and hydrated cowpea were investigated using the method of mixtures. For most of the samples, the specific heat was highest either at 60 degrees or 28.6% moisture content. Further increase beyond these levels resulted in a decrease in the specific heat. Density was determined at room temperature. An initial decrease was observed in density of the samples as moisture level increased from 9.1%, but above 23.1% moisture content, the density increased with higher moisture levels. Thermal conductivity was determined by the line probe method. The thermal conductivity of ground and hydrated cowpea was dependent on moisture content and bulk density but independent of temperature.
