Carbon dioxide (R-744) saturation table by pressure

Name: Carbon dioxide (R-744) saturation table by pressure
Creator: Simuveliq

This table gives saturation temperature and properties of saturated liquid and vapor for each pressure. Above you can use it interactively (switch units with SI/US, pick the pressure or go to the calculator for any point with step-by-step interpolation). Reference state: IIR: h = 200 kJ/kg and s = 1 kJ/kg·K for saturated liquid at 0 °C.
