Formula & correlation notes
  • Saturation (for Tsat): IAPWS Wagner-type p(T); for T from P use Newton with central derivative.
  • Ideal gas: v = R·T/P (with P in bar → ×100 to kPa); ρ = 1/v.
  • Enthalpy (superheated): h ≈ Cp·T + h₀ with h(100 °C,sat)=2676 kJ/kg ⇒ h₀ = 2676 − Cp·Tref.
  • Entropy (superheated): s ≈ sg,ref + Cp·ln(T/Tref) − R·ln(P/Pref).
  • Internal energy: u = h − P·v (P in kPa, v in m³/kg → kJ/kg).
  • Heat capacities: Cv = Cp − R; k = Cp/Cv. (Single-average Cp used.)
