lower limit for calculation: -55 C, 1 bar      upper limit: 900 C, 1000 bar

Pressure:
Temperature:




Calculation of thermodynamic state variables of carbon dioxide at saturation state, boiling curve

lower limit for calculation: -55 C, 5,4 bar bar      upper limit: 30 C, 72,14 bar.

Pressure:
OR
Temperature:

The following thermodynamic properties will be calculated:
density, dynamic viscosity, kinematic viscosity, specific enthalpy, specific entropy, specific isobar heat capacity cp, specific isochor heat capacity cp, thermic conductivity, coefficient of thermal expansion, heat conductance, thermal diffusivity, Prandtl-number, coefficient of compressibility Z, speed of sound.

Calculation of carbon dioxide : if you found an error, please mail to: wischnewski@mpib-berlin.mpg.de. No garanty for correctness.
