The vapour pressure line has a maximum at 94.0° C and a pressure of 82.4 mm Hg. Previously deduced formulae for the calculation of maxima in vapour pressure lines and for the calculation of metastable eutectics, are found in this case also to give good agreement with the experimental ...
7,11,12,17,18,19]). The most serious of the shortcomings [12] lies in the lack of control of water vapour pressure\(p_\textrm{w}\)(or RH) at the specimen surface, especially in the interior of the cup. Since there is a mass flux from the surface of the salt solution or desicc...
To calculate the vapor density of sulfur dioxide (SO₂), we will follow these steps:Step 1: Determine the Molar Mass of Sulfur Dioxide Sulfur dioxide (SO₂) consists of one sulfur (S) atom and two oxygen (O) atoms. We will
7). The calculation based on the kinetic fractionation coefficients of the smooth wind regime leads to an RHsea/d-excess distribution (Fig. 4) with a similar slope as the observations, but is biased towards higher d-excess values (slope of calculated versus measured values m = 0.94, ...
However, very limited information is available on the precision of the IWV determined by radiosondes. In this paper the methodology of the computation of IWV retrieved from radiosonde data is revised using the atmospheric profiles of pressure, relative humidity and temperature. The formulae to ...
the critical pressure method or the thermal expansion coefficient method, or by calculation based on the molecular attraction constant method using the molecular attraction constants proposed by Small, Hoy et al (Hoy K L, J. Paint Technol. 42(541)76-(1970), Small PA, J. Appl. Chem. 3, ...
By introducing a simple quadratic function and using a sectional fitting method,the effect data range of current fast calculation formulae for R410Asaturatedthermal properties was extended to the critical region. 通过引入简单的二次函数并采用分段拟合的方法,将现有的制冷剂R410A饱和区物性快速计算公式的...
Vapor-Liquid Equiibria at High Pressures: Calculation of Partial Molar Volume in Non-Polar Liquid Mixtures Thermodynamic analysis of high-pressure vapor-liquid equilibria requires information on the effect of pressure on liquid phase fugacities; this information is given by partial molar volumes in th...
The coefficients of the series can be obtained from fluctuation formulae by performing grand canonical Monte Carlo (GC MC) simulations on both vapour and liquid sides. It was found that the main shortcoming of the method originates from the inaccurate calculation of the pressure on liquid side ...
A simple approximate relation is derived for the temperature of the maximum occurring in the vapour-pressure lines of saturated solutions of a number of non-volatile substances of high melting point in a volatile solvent. The derivation is analogous to that for saturated solutions of one dissolved...
