The saturated steam table provides the temperature at which water boils at a given pressure (saturation temperature) and the thermodynamic properties of water and steam at this point. This tool calculates the values for your desired pressure using the IAPWS-IF97 international standard, instead of looking values up in a printed table. You can enter the pressure in bar(g), MPa, kg/cm², or psi, and also change the output units.
What do the values in the table mean?
- Saturation temperature: the temperature at which water turns into steam at that pressure.
- hf – saturated water enthalpy: the heat content of 1 kg of water at the boiling point.
- hfg – latent heat of vaporization: the heat required to turn 1 kg of water into steam at the same temperature; this is the energy used in heating processes.
- hg – saturated steam enthalpy: hg = hf + hfg.
- vg and density: used in pipe diameter and steam velocity calculations.
Example
At 10 bar(g) pressure, the saturation temperature is 184.12 °C, the latent heat of vaporization is 1,999.3 kJ/kg, the saturated steam enthalpy is 2,780.7 kJ/kg, and the steam density is 5.642 kg/m³. As pressure increases, the saturation temperature increases, while the latent heat decreases.
Calculations are performed using the IAPWS-IF97 formulation and cover the 0–350 °C saturation range (0.0006–16.5 MPa absolute). For steam boiler selection, you can check our steam boiler guide and get a free quote for your project.
