Critical pressure values for pressure in Van Der Waals equation

Input(s)

P: Pseudocritical Pressure (psi)

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

$\mathrm{T}_{\mathrm{c}}$: Critical Temperature $(\mathrm{K})$

B: Mole Fraction of Hydrogen Sulfide (fraction)

$\varepsilon$: Correlation Constant (dimensionless)

Output(s)

$P_{\mathrm{c}}$: Critical Pressure (psi)

Formula(s)

$$ \mathrm{P}_{\mathrm{c}}=\frac{\mathrm{P} * \mathrm{~T}_{\mathrm{c}}}{\mathrm{T}+\mathrm{B} *(1-\mathrm{B}) * \varepsilon} $$
