Thermodynamic Properties of Saturated Steam: Data & Charts in Bar
Saturated Steam Table with properties like boiling point, specific volume, density, specific enthalpy, specific heat and latent heat of vaporization.
Saturated Steam Properties Reference
Key Parameters
- Absolute Pressure (bar): The absolute pressure of the saturated steam
- Boiling Point (°C): The saturation temperature at the given pressure
- Specific Volume (m³/kg): Volume occupied by 1 kg of steam at saturation
- Density (kg/m³): Mass per unit volume of steam
- Specific Enthalpy of Liquid Water (kJ/kg): Sensible heat required to heat water from 0°C to saturation temperature
- Specific Enthalpy of Steam (kJ/kg): Total heat content of saturated steam
- Latent Heat of Vaporization (kJ/kg): Heat energy required to convert liquid water to steam at constant temperature and pressure
- Specific Heat (kJ/kg·K): Heat capacity of the substance
Important Notes
- Vacuum Steam: Saturated steam at temperatures below 100°C operates at pressures lower than atmospheric pressure
- Pressure Relationship: As pressure increases, the saturation temperature increases, and the latent heat of vaporization decreases
- Specific Volume: Decreases with increased pressure - higher pressure allows more energy transfer in steam distribution systems
- Standard Atmospheric Pressure: 1 bar abs = 0 bar gauge = 100 kPa abs (IUPAC system)
