IAPWS R7-97 Fresh Water Density At Atmospheric Pressure

Calculate IAPWS R7-97 fresh water density from temperature at atmospheric pressure.

The calculation is valid between the melting point (273.15 K), and the boiling point (373.15 K).

Note : There is an anomaly in the steam calculation for region 3 between the saturated vapour line, the region 2/3 boundary, and the critical pressure. Refer to the region 3 anomaly help page for more details (click the utility button on the data bar). IAPWS R7-97 is intended for industrial use, and is a simplified version of IAPWS R6-95 for scientific use. IAPWS R7-97 was developed as an improvement of the IFC-67 model.
