Saturated water and steam properties
Discrete saturation pressure, density, specific volume and enthalpy for saturated water and steam.
Conditions and limits
Each row describes liquid–vapor saturation at the stated temperature. Pressure is the corresponding absolute saturation pressure, not a fixed atmospheric pressure. Liquid is saturated liquid (quality Q=0); vapor is dry saturated steam (Q=1).
Only the listed discrete states from 5 to 200 °C are provided; no interpolation is performed. Subcooled liquid, superheated steam, intermediate wet-steam quality, ice and near-critical states are not covered. At 100 °C, saturation pressure is about 101.418 kPa; at standard atmospheric pressure of 101.325 kPa, boiling occurs near 99.97 °C.
Lookup example
For dry saturated steam at 100 °C, select the 100 °C row: absolute saturation pressure is 101.418 kPa and vapor specific enthalpy is 2675.57 kJ/kg. This is the Q=1 endpoint, not intermediate-quality wet steam; do not interpolate other states.
Filter listed states
Filters listed discrete states only; no calculation, interpolation or phase inference.
Session storage is unavailable. Filtering still works; after changing language selections may reset or revert to older values, so check them.

Method and license
Generated by CoolProp 8.0.0 HEOS::Water (IAPWS-95 equation of state) from temperature and quality Q=0 or Q=1. Latent heat is the vapor enthalpy minus the liquid enthalpy. Enthalpies use the CoolProp default reference state; displayed digits do not imply model accuracy.
The 100 °C row can be checked against NIST steam tables based on IAPWS-95; this comparison uses the same equation-of-state family. NIST Steam Tables.
