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

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
