) As ObjectParameters
- T Double
- Temperature (K) at which to find the dew pressure.
- Vy Object
- Array of vapor-phase (overall) mole fractions.
- VKij Object
- Binary interaction parameter matrix.
- VTc Object
- Array of critical temperatures (K).
- VPc Object
- Array of critical pressures (Pa).
- Vw Object
- Array of acentric factors.
- KI Object
- Array of initial K-value estimates (0 to auto-generate from Raoult's law).
