1. Acetone at 35 °C

from processpi.components.acetone import Acetone
from processpi.units import *

acetone = Acetone(temperature=Temperature(35, "C"))
print(acetone.density().to("kg/m3"))
print(acetone.viscosity().to("Pa·s"))
print(acetone.specific_heat().to("J/kgK"))
print(acetone.thermal_conductivity().to("W/mK"))
print(acetone.vapor_pressure().to("Pa"))
print(acetone.enthalpy().to("J/kg"))

2. Acetone at higher temperature (60 °C) with unit conversion

acetone_high = Acetone(temperature=Temperature(60, "C"))
print(acetone_high.density().to("lb/ft3"))
print(acetone_high.viscosity().to("cP"))

7. Vapor with custom overrides

from processpi.components.vapor import Vapor

custom_vapor = Vapor(
    temperature=Temperature(120, "C"),
    density=Density(0.7, "kg/m3"),
    viscosity=Viscosity(0.00002, "Pa·s"),
    specific_heat=SpecificHeat(1900, "J/kgK"),
)
print(custom_vapor.density().to("kg/m3"))
print(custom_vapor.viscosity().to("Pa·s"))
print(custom_vapor.specific_heat().to("J/kgK"))

8. Quick comparison: Organic vs. Inorganic Liquid

organic_50 = OrganicLiquid(temperature=Temperature(50, "C"))
inorganic_50 = InorganicLiquid(temperature=Temperature(50, "C"))

print(organic_50.density().to("kg/m3"))
print(inorganic_50.density().to("kg/m3"))
print(organic_50.viscosity().to("Pa·s"))
print(inorganic_50.viscosity().to("Pa·s"))

9. Water at room temperature

print(water.thermal_conductivity().to("W/mK"))
print(water.vapor_pressure().to("Pa"))

10. Toluene at 50 °C

from processpi.components.toluene import Toluene

toluene = Toluene(temperature=Temperature(50, "C"))
print(toluene.density().to("kg/m3"))
print(toluene.viscosity().to("Pa·s"))
print(toluene.specific_heat().to("J/kgK"))
print(toluene.vapor_pressure().to("Pa"))

11. Methanol at 30 °C

from processpi.components.methanol import Methanol

methanol = Methanol(temperature=Temperature(30, "C"))
print(methanol.density().to("kg/m3"))
print(methanol.viscosity().to("Pa·s"))
print(methanol.specific_heat().to("J/kgK"))
print(methanol.thermal_conductivity().to("W/mK"))
print(methanol.vapor_pressure().to("Pa"))

✅ Summary

Every fluid is represented as a class (e.g., Water, Acetone, Oil, Gas).

Properties available: density(), viscosity(), specific_heat(), thermal_conductivity(), vapor_pressure(), enthalpy().

Values can be converted to engineering units via .to("").

Custom overrides are supported for flexibility.

This system supports realistic chemical & process engineering workflows.
