Calculation of thermodynamic state variables of oxygen

lower limit for calculation: -200 C, 1 bar      upper limit: 100 C, 500 bar

Pressure:
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 oxygen : if you found an error, please mail to: wischnewski@mpib-berlin.mpg.de. No garanty for correctness.
