A Formulation of the Thermodynamic Properties of Ordinary Water Substance
According to the International Formulation Committee of the International Conference on the Properties of Steam, a formulation of the properties of steam is determined in the present paper. The formulation covers the whole region of the International Skeleton Table of 1963, that extends in pressure from the ideal gas limit (at zero pressure) to a pressure of 10⁸N/m² (1000 bar), and that extends in temperature from 273.16°K (0.01°C) to 1073.15°K (800°C). This whole region is devided into seven sub-regions, and is expressed by the four major functions, namely, the function A (for liquid water region), the function B (for superheated steam region), the function C (for critical region above critical temperature) and the function D (for critical region below critical temperature). The discontinuities of the properties at the boundaries between the sub-regions are calculated and discussed
On the Relation between Total and Partial Pressure of Gas Mixture
It may be inadequate, in general, to apply Dalton's law to an imperfect gas mixture. In this paper, the total pressure of an imperfect gas mixture is considered from the view point of statistical mechanics. Namely, by expressing the equation of state in the virial expansion form, the total pressure of a gas mixture was determined analytically by using the second and the third virial coefficients calculated from the values for each component gas. For one example, the second and third virial coefficients of air were calculated by two methods and compared with each other as well as with other values which were determined directly from experimental data with air. From the numerical calculations for air and also for water-mercury vapour mixture, it has been made clear that there is some difference between the total pressure calculated by our methods and the value calculated from Dalton's law, and this difference increases with the degree of imperfectness of the gas mixture
Pressure Dependence of Viscosity of Polar Gases
Viscosity of polar gases, such as steam and ammonia, decreases with increasing pressure. In order to explain this anomaly, we considered a polar gas to be a mixture of dimers and monomers. The viscosity of steam and ammonia was calculated as the sum of mixture term ηₘᵢₓ and collisional transfer term ηc, namely η=ηₘᵢx+ηc. The calculated and experimental values of viscosity of these gases agreed qualitatively well, and the negative pressure dependence of viscosity of these gases was explained with reasonable success by the theory of association
