Class Reference

class BenzoicAcid()

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

Methods

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

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