Calculation of Thermodynamic properties of Fluid Using a New Equation of State
Authors
Abstract:
Using the Lennard-Jones (12-6) potential, a new equation of state is obtained that can predict properties of both gases and liquids relatively well. This equation of state is given as (Z-a)V2=(A/V2)-B, where Z is the compressibility factor, A and B are constants, and a is an adjustable parameter that depends on the temperature, volume and the nature of the fluid, and its expressions depends upon the fluid status. In this paper, appropriate expressions for argon are given for a, in the liquid region when 0.6r<1, and in the gaseous region when 1.1r

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
