Saturated Steam Table Calculator
In thermodynamics and mechanical engineering, saturated steam tables are essential for analyzing heat transfer, power cycles, and energy systems. However, reading printed steam tables or interpolating values manually can be time-consuming and prone to error. A Saturated Steam Table Calculator simplifies this process by providing instant access to key steam properties using either temperature or pressure as input.
This calculator allows users to determine important thermodynamic properties of saturated water and steam accurately, making it an invaluable tool for students, engineers, and professionals working in thermal sciences.
What Is a Saturated Steam Table?
A saturated steam table lists thermodynamic properties of water and steam at saturation conditions. Saturation occurs when liquid water and vapor coexist in equilibrium at a given temperature and pressure.
At saturation, every temperature corresponds to a unique pressure and vice versa. The steam table provides properties such as:
- Specific volume
- Enthalpy
- Entropy
- Saturation temperature or pressure
These values are critical for analyzing boilers, turbines, condensers, and refrigeration systems.
