Peng Robinson PVT equation
Input(s)
R: Gas Constant (BTU/psi K mol)
\(\mathrm{T}\): Temperature \((\mathrm{K})\)
\(\mathrm{V}\): Volume \(\left(\mathrm{ft}^{3}\right)\)
a: Correlation Constant (dimensionless)
b: Correlation Constant (dimensionless)
Output(s)
P: Pressure \((\mathrm{psi})\)
Formula(s)
\[
\mathrm{P}=\frac{\mathrm{R} * \mathrm{~T}}{\mathrm{~V}-\mathrm{b}}-\frac{\mathrm{a} * \mathrm{~T}}{\mathrm{~V} *(\mathrm{~V}+\mathrm{b})+\mathrm{b} *(\mathrm{~V}-\mathrm{b})}
\]
