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.

To understand the behaviour of real gases, the following must be taken into account:. Information about reproducing material from RSC articles with different licences is available on our Permission Requests page.
It has five experimentally determined constants. The compressibility factor Z is a dimensionless ratio of the product of pressure and specific volume to the product of gas constant and temperature.
Equations of State
It is expressed as. In the vicinity of the critical point, the gases deviate from ideal gas greatly.
For reproduction of material from PCCP: However, it is only accurate over a limited range. Reproduced material should be attributed as follows: Z can be either greater or less than 1 for real gases.
Where p is the pressure, T is the temperature, R the ideal gas constant, and V m the molar volume. The Beattie-Bridgeman equation of state was proposed in The further away Z is from unity, the more the gas deviates from the ideal-gas behavior. The Redlich—Kwong equation is another two-parameter equation that is used to model real gases.
Any equation that relates the pressure, temperature, and specific volume of a substance is called the equation of state. The properties with a bar on top are molar basis. For reproduction of material from all other RSC journals and books: Jump to bridggeman content.

The animation on the left shows the error involved in assuming steam to be an ideal gas. Robinson  has the interesting property being useful in modeling some liquids as well as real gases.
