nH2O is a Reference app by nHance Technologies Inc.. nH2O is a “water property” calculator that calculates various thermodynamic properties of steam and water. nH2O is based upon the Modular Modeling System (MMS) steam property library which is composed of a set of routines, some polynomials and some table interpolations of the thermodynamic properties of steam and water.

1. In general, all subcooled liquid and superheated vapor of steam properties are accurate to +/- 0.24% within a pressure range of 0.01 to 6,000 psia and enthalpy ranges from 100 btu/lbm to 1600 btu/lbm outside the saturation region.

3. nH2O is a “water property” calculator that calculates various thermodynamic properties of steam and water.
4. Calculated properties include Pressure (P), Temperature (T), Enthalpy (h), Entropy (s), Specific Volume (v), Density (ρ), and Quality (x).
5. Saturated properties are accurate to within +/- 0.24% from 0.1 psia to 3,200 psia within the saturated region.
6. ** NOTE: The functions used in the nH2O calculator are designed for dynamic thermodynamic simulation.
7. They are generally accurate to within 1% of conventional routines, but are NOT identical to ASME, IAPWS, or IFC formulations.
8. Support is provided for both US Conventional units, and Conventional SI units.

I've compared the results with other tables and they are wrong. Wrong enough to not use it for engineering
The saturation temperatures do not match up with the saturation pressures correctly. A good example is at 27 C. The enthalpy should be ~113 but it is ~123. The app is good for rough calculations. If they fixed the saturation temperatures and pressures then it would be 5 stars.
As a mechanical engineer, this app really helps and saves me a lot of time.
Very reliable free app for steam tables
I use it for telling me what my super heat is at while starting up a power plant. It would be nice if it just told me how much super heat I have. Instead of going off of the heat above saturation temp but it works. Thank you for making the app!!!
