A New Vapor Pressure Equation
The Wagner equation for prediction of vapor pressure has been modified in order to improve it accuracy. On the basis of this modifications, development of a new equation for prediction of vapor pressure is outlined. Examples of the use of the equation for obtaining vapor pressure for a total of 94 pure substance are given. The proposed equation combines simplicity and accuracy and performs as w...
متن کاملPressure Dependence of Liquid Vapor Pressure: An Improved Gibbs Prediction
A new model for the vapor phase of a pressurized liquid called "the cluster model: which is originally introduced in this work, along with an accurate equation of state for the liquid phase called the LIR, is used to derive an accurate equation for the vapor pressure of liquid as a function of external pressure. The chemical Potential of both phase have been found to be in good agreement wi...
متن کاملTests with Separated Tables for Water Vapor Saturation Pressure over Ice and Water
A modiied water vapor saturation pressure table, containing both water vapor saturation pressure over ice and over water have been introduced in HIRLAM and compared to the reference table, where one single mixed table is used. Diierent aspects of how to use this new vapor saturation pressure table are treated in this report and two tests with it are presented. The best result is obtained when t...
متن کاملCharging of ice-vapor interfaces
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract The build-up of intrinsic Bjerrum and ionic defects at ice-vapor interfaces electrically charges ice surfaces and thus gives rise to many phenomena including thermoelectric-ity, ferroelectric ice films, sparks from objects in blizzards, electromagnetic em...
متن کاملCriteria for Establishing Accurate Vapor Pressure Curves
We use standard thermodynamic relationships to demonstrate the accuracy of new vapor pressure measurements by using them in the calculation ofliquid-phase heat capacities and comparing the results with recently published experimental values. Results for the new alternative refrigerants Rl34a and R 123 are used as examples.
