Pseudo-reduced conditions
Input(s)
P: Pressure (psi)
\(P_{c A}\): Critical Pressure at A (psi)
\(P_{c B}\): Critical Pressure at B \((\mathrm{psi})\)
\(\mathrm{T}\): Temperature \((\mathrm{K})\)
\(T_{c A}\): Critical Temperature at \(\mathrm{A}(\mathrm{K})\)
\(T_{c B}\): Critical Temperature at B (K)
Output(s)
\(P_{r}\): Pseudo Reduced Pressure (dimensionless)
\(T_{r}\): Pseudo Reduced Temperature (dimensionless)
Formula(s)
\[
\begin{aligned}
& \mathrm{P}_{\mathrm{r}}=\frac{\mathrm{P}}{\left(\mathrm{P}_{\mathrm{cA}} * \mathrm{P}_{\mathrm{cB}}\right)^{0.5}} \\
& \mathrm{~T}_{\mathrm{r}}=\frac{\mathrm{T}}{\left(\mathrm{T}_{\mathrm{cA}} * \mathrm{~T}_{\mathrm{cB}}\right)^{0.5}}
\end{aligned}
\]
