This equation is known to herthelot reasonably accurate for densities up to about 0. Cengel and Michael A. Van Wylen and Richard E. Views Read Edit View history. It is expressed as. The Clausius equation named after Rudolf Clausius is a very simple three-parameter equation used to model gases.

From Wikipedia, the free encyclopedia. The Wohl equation named after A.


Real gas – Wikipedia

To understand the behaviour of real gases, the following must be taken ecuxcion account:. It is almost always more accurate than the van der Waals equationand often more accurate than some equations with more than two parameters.

Retrieved from ” https: 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. Berthelot [1] is very rarely used.

To understand the behaviour of real gases, the following must be taken into account: The Virial equation derives from a perturbative treatment of statistical mechanics. For most applications, such a detailed analysis is unnecessary, and the ideal gas approximation can be used with reasonable accuracy.

This model named after C. 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. These parameters can be determined:.


Robinson [3] has the interesting property being useful in modeling some liquids as well as real gases. Where p is the pressure, T is the temperature, R the ideal gas constant, and V m the molar volume.

Wohl [4] is formulated in terms of 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 ds the critical volume. Industrial and Engineering Chemistry: Real gases are non-hypothetical gases whose molecules occupy space and have interactions; consequently, they adhere to gas laws.
