Formula 8.30
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)
$$ \begin{aligned} & \mathrm{P}_{\mathrm{r}}=\frac{\mathrm{P}}{\left(\mathrm{P}_{\mathrm{cA}} * \mathrm{P}_{\mathrm{cB}}\right)^{0.5}} \\ & \mathrm{~T}_{\mathrm{r}}=\frac{\mathrm{T}}{\left(\mathrm{T}_{\mathrm{cA}} * \mathrm{~T}_{\mathrm{cB}}\right)^{0.5}} \end{aligned} $$
