Class: `Chloromethane`

Description

The Chloromethane class represents the properties and constants for Chloromethane (CH₃Cl).
It provides physical and thermodynamic properties required in process engineering simulations and calculations.

Properties

name (string): Chloromethane
formula (string): CH₃Cl
molecular_weight (float): 50.49 g/mol

Class Reference

class Chloromethane()

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

phase(): Detects the phase of the substance ("gas" or "liquid") by comparing the system temperature and vapor pressure.
density():
Gas Phase: Uses the Ideal Gas Law
Liquid Phase: Uses DIPPR or experimental 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 vapor pressure (Pvap) using an Antoine-type correlation
enthalpy(): Calculates the enthalpy of vaporization (ΔHvap) using a correlation based on reduced temperature
