Ideal Gas Model

Many of the conventional results obtained when optimising the performance of an intercooler during compression using a perfect gas model can be obtained when the restrictions of the model are relaxed to an ideal gas. That is, we now have temperature-dependent specific heat capacities but retain the equation of state pV = RT. This note illustrates the theme.

Thermal properties (Density, Thermal conductivity and Specific heat capacity) play important impact in the formation of devicesmade of wooden materials. This study examines the room temperature thermal response of ten bulk samples from the species of Pterygota macrocarpa and Antiaris africana wood species found in South Western Nigeria. The samples were processed into appropriate shapes to fit into the parallel plane arrangement to determine the thermal properties. Temperature dependent models were used to obtain the specific heat capacities of the samples within a temperature variation of 308.25𝐾 - 310.00𝐾. The results revealed that the thermal properties (thermal conductivities and specific heat capacities) increase as temperature increases for all the bulk samples considered. The results of the research showed that the selected wood samples could find useful applications in industrial insulating devices. Keywords: Wood material, Lee’s disc apparatus, Temperature and Thermal properties.
