  • molecular_weight (float): Molar mass in g/mol

Class Reference

class Acetone()

Parameters:
temperature: Temperature, default = Temperature(35,"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 AceticAcid 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 calculated vapor pressure. The rule is: "gas" if P < Pvap,​ otherwise "liquid".
  • density():

    • Gas Phase: Calculates density using the Ideal Gas Law

    • Liquid Phase: Calculates density using the DIPPR correlation

  • specific_heat(): Calculates specific heat capacity (Cp​) as a polynomial function of temperature

  • viscosity():

    • Liquid Phase: Calculates viscosity (μ) using the DIPPR correlation:

    • Gas Phase: Calculates viscosity using Sutherland's Law.

  • thermal_conductivity(): Calculates thermal conductivity (k) as a polynomial function of temperature

  • vapor_pressure(): Calculates vapor pressure (Pvap​) using the Antoine-style equation

  • enthalpy(): Calculates the enthalpy of vaporization (ΔHvap​) using a correlation based on reduced temperature
