Pseudo-reduced conditions

Input(s)

P: Pressure (psi)

PcAP_{c A}: Critical Pressure at A (psi)

PcBP_{c B}: Critical Pressure at B (psi)(\mathrm{psi})

T\mathrm{T}: Temperature (K)(\mathrm{K})

TcAT_{c A}: Critical Temperature at A(K)\mathrm{A}(\mathrm{K})

TcBT_{c B}: Critical Temperature at B (K)

Output(s)

PrP_{r}: Pseudo Reduced Pressure (dimensionless)

TrT_{r}: Pseudo Reduced Temperature (dimensionless)

Formula(s)

Pr=P(PcAPcB)0.5 Tr=T(TcA TcB)0.5\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}
