This primer is of general technical interest for end use in projects

1. IAPWS Region 1 contents most use properties in Engineering works.
2. Water [kg/m³] ...... => high accuracy
3. Water bar saturation => high accuracy
4. Viscosity Water .... => high accuracy

All formulas meet or better than any on-line calculators.
Nothing is exactly true in those properties.

Enjoy/comment, welcome.
