About Saturated Steam Properties
The Saturated Water – Pressure Table provides essential thermodynamic property data for water and steam in equilibrium. Engineers, students, and HVAC professionals use these values for Rankine cycle analysis, boiler and turbine design, refrigeration systems, and HVAC calculations. Each property helps describe how water transitions from liquid to vapor at a specific pressure and temperature.
- Pressure (kPa) – The primary variable controlling saturation conditions. At each pressure, water and steam coexist in equilibrium. This table expresses steam properties as a function of pressure, vital for thermodynamic cycle and boiler design calculations.
- Saturation Temperature (°C) – The boiling or condensation temperature at the given pressure. This value is key for determining operating conditions in power plants and HVAC systems.
- Enthalpy (h) – Total heat energy per kilogram of water/steam. hf is the enthalpy of the saturated liquid, hfg is the latent heat of vaporization, and hg represents the enthalpy of saturated vapor. These values are critical for energy balance, heat input, and cycle efficiency calculations.
- Specific Volume (v) – Space occupied by 1 kg of substance. vg represents the saturated vapor volume, used for turbine, pump, and pipe flow calculations.
Using this table, engineers can accurately determine steam quality, latent heat, phase-change behavior, and thermodynamic performance under different operating pressures. Reference this saturated steam table by pressure for practical engineering, energy conversion, and thermodynamic research.
