Kalkulator sifat termodinamika dan thermophysical

Thermodynamic and thermophysical calculator.

Allows you to calculate thermodynamic properties:

- Temperature, Pressure, Volume, Vapour Fraction, Enthalpy, Entropy by Peng-Robinson (1975) EOS

- Liquid density by Yen-Woods eq.

- Heat of evaporation (EOS)

- Cp – heat capacity isobaric (EOS)

- Cv – heat capacity isochoric (EOS)

- sonic speed (EOS)

- adiabatic coefficient (EOS)

Thermophysical properties:

- Thermal conductivity (Stiel-Thodost eq. for gases, polynomial for liquid)

- Viscosity (Jossi-Stiel-Thodost eq. for gases, polynomial for liquid)

- Surface tension (Guggenheim-Katayama)

You can calculate thermodynamic characteristics of some apparatus:

- Heat exchanger

- Isoenthalpic valve

- Polytropic compressor

- Isothermal compressor (multistage)

- Polytropic expander

Available elements for calculations:

methane, ethane, propane, n-butane, i-butane, n-pentane, i-pentane, n-hexane, n-heptane, n-octane, nitrogen, ammonia, oxygen, argon, R134a, R21, R22, R23, R507, H2O, acetone, F6S.
