Superheated steam is steam that is hotter than the saturation temperature at its given pressure. It is used in turbines, long steam lines, and processes requiring high temperatures. This tool calculates the properties of superheated steam (region 2) and viscosity using the IAPWS-IF97 and IAPWS-2008 standards, respectively, when you input pressure and temperature.
Calculated values
- Enthalpy (h), specific volume (v), and density
- Specific heat (cp) and entropy (s)
- Dynamic viscosity (for pressure drop calculations)
- Saturation temperature at that pressure and degree of superheat
Example
At 10 bar(g) pressure and 250 °C temperature, the enthalpy of steam is 2,939.4 kJ/kg, and the specific volume is 0.2105 m³/kg. Since the saturation temperature at this pressure is 184.12 °C, the degree of superheat is 65.9 °C.
The temperature must be higher than the saturation temperature at the entered pressure and should not exceed 800 °C.
