Reference
What the steam table values mean
Saturation pressure
The pressure at which liquid water and steam coexist at a given saturation temperature.
Specific volume
Volume occupied per kilogram, used for pipe flow, turbine, compressor, and vessel estimates.
Enthalpy
Energy content per kilogram, used in boiler heat input, turbine work, and condenser calculations.
Entropy
Thermodynamic property used for ideal expansion, irreversibility, and Rankine cycle analysis.
FAQ
Steam table questions
What is a saturated steam pressure table?
It lists saturation temperature and steam properties at selected pressures where liquid water and steam can coexist.
Why use a pressure-based steam table?
Many boilers, condensers, and pressure vessels are specified by pressure, so a pressure table makes operating-point lookup faster.
Can these values replace formal steam software?
No. Use this page for quick reference and learning. Final design work should use validated steam tables, IAPWS data, and engineering standards.
