The gold standard, though usually paid, there are limited free versions or online calculators based on its data.
If your input (e.g., 210°C) falls between two table entries (200°C and 220°C), the software performs linear interpolation automatically. It displays both the raw table data and the calculated result.
Let’s say you need the enthalpy at the turbine inlet (10 MPa, 500°C):
Instantly find pressure, temperature, specific volume, enthalpy, and entropy.
