Class: `Water`

Description

The Water class represents water in liquid or vapor (steam) phase.
It provides physical and thermodynamic properties required in process engineering simulations and calculations.
All properties can be retrieved from CoolProp for accurate temperature- and pressure-dependent values.

Properties

name (string): Water
formula (string): H₂O
molecular_weight (float): 18.015 g/mol

Class Reference

class Water()

Parameters:
temperature: Temperature, default = Temperature(25,"C")
pressure: Pressure, default = Pressure(1,"atm")

Methods

The properties of the Water class are obtained using CoolProp:

phase(): Returns "liquid", "gas", or "two-phase" depending on temperature and pressure.
density(): Returns the density (ρ) at the given temperature and pressure.
specific_heat(): Returns the specific heat capacity at constant pressure (Cp).
viscosity(): Returns the dynamic viscosity (μ).
thermal_conductivity(): Returns the thermal conductivity (k).
vapor_pressure(): Returns the saturation pressure at the given temperature.
enthalpy(): Returns the enthalpy (h) per unit mass.

All calculations are accurate and sourced directly from CoolProp.

Examples

from processpi.components import Water
from processpi.units import *

# Create a Water object at 150°C
water = Water(temperature=Temperature(150, "C"))

print("Density:", water.density().to("kg/m3"))
print("Viscosity:", water.viscosity().to("Pa·s"))
print("Specific Heat:", water.specific_heat().to("J/kgK"))
print("Thermal Conductivity:", water.thermal_conductivity().to("W/mK"))
print("Vapor Pressure:", water.vapor_pressure().to("Pa"))
print("Enthalpy:", water.enthalpy().to("J/kg"))
print("Phase:", water.phase())
