The functional expressions of these parameters, which are generalized as a function of the acentric factor omega and the reduced temperature T//r, were determined separately in the temperature ranges T less than T//c//r and T greater than T//c//r. As a result, it is possible for an ...
Vapor pressure of air can be determined from paired measurements of relative humidity and air temperature, which are commonly available, or from measurement of dew-point temperature, also commonly available. Vapor pressure inside the soil or plant surface is rarely measured, however, so that, as ...
Calculating dew point and bubble point of gas mixtures In the picture above, the C is the critical point. There seems to be some easy methods to calculate the critical temperature, but not so with the critical pressure. For bubble point it would give me ... Johan A 171 answered May ...

interface. The EES_REFPROP interface dated May 3, 2023 optionally allows data points to be calculated within the vapor dome for constant temperature and pressure lines. This capability can be useful for mixtures in which the temperature or pressure is not the same for saturated liquid and vapor....

They also explored the Soave [4] and Stryjek & Vera [49], [50] approaches on the temperature dependence of α. This last point has been extended by the recent work made by Young et al. [51], who evaluated the performance for Psat prediction of 20 different α functions in PR (...

The paper also develops a new two-parameter, temperature-dependent equation. The new model accurately predicts pure component major pressure and shows excellent extrapolation characteristics when used for calculating equilibrium in mixtures that contain one or more supercritical components. Finally, the ...
The Antoine equation, which solves this problem for pure components, is due to a French engineer (Louis Charles Antoine, 1825–1897) and was first published in " Annales de Physique et de Chimie " in 1891 (Antoine 1891 ). Antoine introduced an equation able to predict the vapor pressure ...
