Beattie-Bridgeman Equation of State: The Beattie-Bridgeman equation of state was proposed in It has five experimentally determined constants. A some what more complex equation is the Beattie-Bridgeman equation. P = R T d + (B R T – A – R c / T2) d2 + (- B b R T + A a – R B c / T2) d3 + R B b c d4 / T2. Orig.

Views Read Edit View history. A gas that obeys this relation is called an ideal gas. Back to tab navigation Fetching data from CrossRef. The first page of this article is displayed as the abstract.

For reproduction of material from PCCP: From Wikipedia, the free encyclopedia. In the vicinity of the critical point, the gases deviate from ideal gas greatly. Dieterici [2] fell out of usage in recent years. The animation on the left shows the error involved in assuming steam to be beattue ideal gas. Real gases are non-hypothetical gases bridgemah molecules occupy space and have interactions; consequently, they adhere to gas laws.

This equation is known to be reasonably accurate for densities up to about 0. For most applications, such a detailed analysis is unnecessary, and the ideal gas approximation can be used with reasonable accuracy.


The Virial equation derives from a perturbative treatment of statistical mechanics. Peng—Robinson equation of state named after D. Industrial and Engineering Chemistry: The following equation is the ideal-gas equation of state.

They are plotted as a function of the reduced pressure and reduced temperature, which are defined as follows: You do not have JavaScript enabled.

The ideal-gas equation of state is very simple, but its application range is limited. By using this site, you agree to the Terms of Use and Privacy Policy. Fetching data from CrossRef.

The Beattie-Bridgeman equation of state was proposed in The compressibility factor Z is a measure of deviation from the ideal-gas behavior. Retrieved from ” https: 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.
