Class: `CarbonDioxide`

Description

The CarbonDioxide class represents the properties and constants for Carbon Dioxide (CO₂).
It provides physical and thermodynamic properties required in process engineering simulations and calculations.

Properties

name (string): Carbon Dioxide
formula (string): CO₂
molecular_weight (float): 44.01 g/mol

Class Reference

class CarbonDioxide()

Parameters:
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 CarbonDioxide class are calculated using the following methods, which are inherited from the base Component class.

phase(): Detects the phase of the substance ("solid", "gas", or "liquid") by comparing the system temperature and pressure to sublimation/vapor pressure.
density():
- Gas Phase: Calculates density using the Ideal Gas Law
- Liquid Phase: Uses DIPPR correlation
specific_heat(): Calculates specific heat capacity (Cp) as a polynomial function of temperature
viscosity():
- Gas Phase: Uses Sutherland’s Law
- Liquid Phase: Uses DIPPR correlation
thermal_conductivity(): Calculates thermal conductivity (k) as a polynomial function of temperature
vapor_pressure(): Calculates sublimation or vapor pressure (Pvap) using Antoine-type correlations
enthalpy(): Calculates enthalpy of vaporization or sublimation (ΔHvap/ΔHsub) depending on phase
