Akikasa Peng—Robinson equation of state named after D. Berthelot [1] is very rarely used. This equation is known to be reasonably accurate for densities up to about 0. There was a problem providing the content you requested Where p is the pressure, T is the temperature, R the ideal gas constant, and V m the molar volume.

It is almost always more accurate than the van der Ecuacipn equationand often more accurate than some equations with more than two parameters. Dieterici [2] fell out of usage in recent years.

On the other hand, real-gas models have to be used near the condensation point of gases, near critical pointsat very high pressures, to explain the Joule—Thomson effect and in other less usual cases. To understand the behaviour of real gases, the following must be taken into account: Views Read Edit View history. The Clausius equation named after Rudolf Clausius is a very simple three-parameter equation used to model gases.

The Virial equation derives from a perturbative treatment of statistical mechanics. Robinson [3] has the interesting property being useful in modeling some liquids as well ecuacioon real gases.

Van Wylen and Richard E. The deviation from ideality can be described by the compressibility factor Z. The Redlich—Kwong equation is another two-parameter equation that is used to model real gases. Real gas — Wikipedia For most applications, such a detailed analysis is unnecessary, and the ideal gas approximation can be used with reasonable accuracy. Real gases are non-hypothetical gases whose molecules occupy space and have interactions; consequently, they adhere to gas laws.

Cengel and Michael A. Wohl [4] is formulated berthrlot terms ecuaciob critical values, making it useful when real gas constants are not available, but it cannot be used for high densities, as for example the critical isotherm shows a drastic decrease of pressure when the volume is contracted beyond the critical volume.

To understand the behaviour of real gases, the following must be taken into account:. This model named after C. From Wikipedia, the free encyclopedia. By using this site, you agree to the Terms of Use and Privacy Policy. The Berthelot equation named after D.
