* temperature: Temperature, default = Temperature(25,"C")
* pressure: Pressure, default = Pressure(1,"atm")
* density: Density, default = None
* specific_heat: SpecificHeat, default = None
* viscosity: Viscosity, default = None
* thermal_conductivity: ThermalConductivity, default = None
* vapor_pressure: Pressure, default = None
* enthalpy: HeatOfVaporization, default = None

Methods

The properties of the CarbonMonoxide class are calculated using the following methods, which are inherited from the base Component class.

phase(): Detects the phase of the substance ("gas" or "liquid") by comparing the system pressure to the vapor pressure. (At standard conditions, CO is a gas.)
density():
- Gas Phase: Calculates density using the Ideal Gas Law
- Liquid Phase: Uses DIPPR correlation (cryogenic conditions)
specific_heat():
- Gas Phase: Ideal-gas heat capacity (Cp), DIPPR Eq. 107 with the constants of Perry's Chemical Engineers' Handbook, 8th ed., Table 2-156
- Liquid Phase: Perry's Table 2-153, Eq. (2), a function of reduced temperature
viscosity():
- Gas Phase: Uses Sutherland’s Law
- Liquid Phase: Uses DIPPR correlation
thermal_conductivity():
- Gas Phase: Vapor thermal conductivity (k), DIPPR Eq. 102 with the constants of Perry's 8th ed., Table 2-314
- Liquid Phase: Polynomial function of temperature (Perry's Table 2-315)
vapor_pressure(): Calculates vapor pressure using Antoine-type correlations (applicable in cryogenic range)
enthalpy(): Calculates enthalpy of vaporization (ΔHvap) using a correlation based on reduced temperature
