Class: `Cyclohexane`

Description

The Cyclohexane class represents the properties and constants for Cyclohexane (C₆H₁₂).
It provides physical and thermodynamic properties required in process engineering simulations and calculations.

Properties

name (string): Cyclohexane
formula (string): C₆H₁₂
molecular_weight (float): 84.16 g/mol

Class Reference

class Cyclohexane()

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 Cyclohexane class are calculated using the following methods, inherited from the base Component class.

phase(): Detects the phase of the substance ("liquid" or "gas") by comparing the system temperature and vapor pressure.
density():
Liquid Phase: Uses DIPPR or experimental correlation
Gas Phase: Uses the Ideal Gas Law
specific_heat(): Calculates specific heat capacity (Cp) as a polynomial function of temperature
viscosity():
Liquid Phase: Uses 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
