Critical pressure values for pressure in Van Der Waals equation

Input(s)

P: Pseudocritical Pressure (psi)

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

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

B: Mole Fraction of Hydrogen Sulfide (fraction)

ε\varepsilon: Correlation Constant (dimensionless)

Output(s)

PcP_{\mathrm{c}}: Critical Pressure (psi)

Formula(s)

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