Description

A water property calculator that uses the Modular Modeling System (MMS) steam property library to calculate various thermodynamic properties of steam and water. It provides accurate values for Pressure, Temperature, Enthalpy, Entropy, Specific Volume, Density, and Quality within specific pressure and enthalpy ranges. Saturated properties are accurate to within +/- 0.24% from 0.1 to 3,200 psia.

From the developer:

nH2O is a “water property” calculator that calculates various thermodynamic properties of steam and water. The app 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.

You may want to check out more Mac applications, such as Calculus, Metes and Bounds or Geometry, which might be similar to nH2O.
