About Superheated Steam Properties
The Superheated Steam Table provides essential thermodynamic property data for steam at temperatures above the saturation point. Superheated steam is steam heated beyond its boiling point at a given pressure, meaning it contains no water droplets and can expand to do work without condensation.
- Pressure (kPa) – Determines the boiling point and thermodynamic state for superheated steam, critical for turbine inlet conditions and Rankine cycle calculations.
- Temperature (°C) – The temperature of steam above saturation; key for heat transfer, turbine performance, and superheated steam system design.
- Specific Volume (v) – Volume occupied per kilogram of steam, essential for flow analysis, expansion devices, and turbine sizing.
- Enthalpy (h) – Total energy content per kilogram of superheated steam, used to calculate heat input, work output, and cycle efficiency.
- Entropy (s) – Measures energy dispersal and system irreversibility, important for thermodynamic cycle analysis and performance evaluation.
Using this table, engineers can accurately calculate work output, heat transfer, turbine efficiency, and performance of thermodynamic systems. Reference this superheated steam table for practical engineering, power plant design, and HVAC applications.
