Superheated steam 200,220.& 250o C

Steam Tables SI units

Important Note
These tables have been compiled, by hand, from calculators available on the internet they are only suitable for rough calculations and there may be typos.  For serious work please use more reliable data.  I provide links below and recommend for serious work that you use the information from these links> (The NIST link probably the best.) I have checked various values and they seem match (to the NIST data) to within about 0,01%
  • P = Pressure..Bara
  • t = oC
  • v Specific Volume..m3 /kg
  • h = Enthalpy..kJ/kg
  • s = Entropy..kJ/kg
  • u = Internal Energy..kJ/kg
T = 200o C
