A Modified Redlich-Kwong Equation For Nonpolar And Slightly Polar Gases, David G. Skamenca
A Modified Redlich-Kwong Equation For Nonpolar And Slightly Polar Gases, David G. Skamenca
Theses
The PVT prediction capability of the Redlich-Kwong equation is substantially improved through the use of a generalized correlation based on the acentric factor. No experimental data is required to obtain the improved constants. Only the acentric factor and the critical properties of the pure gas are needed. The correlation of improved constants is limited to non-polar and slightly polar pure gases and mixtures in the supercritical temperature range.
The correlation applies to a reduced temperature range 1.00 le; TR le; 1.60 and a reduced pressure range of 0.030 le; PR le; 3.00. The correlation reduces deviations by as …
Correlation And Prediction Of Diffussion Coefficients In Binary Gas Systems, Raymond Gerald Bailey
Correlation And Prediction Of Diffussion Coefficients In Binary Gas Systems, Raymond Gerald Bailey
Theses
A correlation was developed for estimating binary gas diffusion coefficients by the reference substance method, in this case using the viscosity of air and subsequently its corresponding temperature. The derivation was made by the linear least square analysis of 65 different binary systems comprising 161 separate data points at temperatures ranging from 193°K. to 1200°K. At any given temperature only the critical molal volume and the molecular weights of the two gases of interest are required to calculate the diffusion coefficient. The correlation based on the viscosity of air had an average error of 7.67%. The correlation using temperature had …
An Investigation Of A Gas Measurement Technique Employing Ultraviolet Excitation, Alphonso Vincent Diaz
An Investigation Of A Gas Measurement Technique Employing Ultraviolet Excitation, Alphonso Vincent Diaz
Physics Theses & Dissertations
A study was undertaken to determine the general applicability of a temperature measurement technique which uses the fluorescence stimulated by a vacuum ultraviolet continuum as the indicator. This study was directed toward determining the temperature of nonradiating carbon monoxide. A number of ultraviolet radiation sources which produced high intensity in the region of l,150 A were investigated. This study led to the conclusion that the technique was not applicable to measurements in carbon monoxide within the present limits of' detectability.
