Abstract

The thermal properties - thermal conductivity, specific heat capacity and viscosity of raphia gum are studied experimentally. The results show that thermal conductivity varies from 0.0164 to 0.0403 (W/mok) for moisture content and temperature ranging from 59.77 to 93.13% (W.b) and 40 to 80 (oC) respectively. The specific heat capacity is from 1.178 to 1.315 (KJ/kgoC) for moisture content and temperature of 59.77 to 70.06% (W.B) and 50 to 70 (oC) respectively. The gum is a non-Newtonian pseudoplastic fluid and hence its viscosity is determined from the shear rate against shear stress plot.
