WebbIn 1997, the IAPWS release the “ IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam ” or IAPWS-IF97. This formulation replaced the older IFC-67 formulation. It is pressure based (rather than density based), and uses fundamental equations for the Gibbs free energy and its derivatives. WebbViscosity is not part of IAPWS Steam IF97. Equations from "Revised Release on the IAPWS Formulation 1985 for the Viscosity of Ordinary Water Substance", 2003 are used. Viscosity in the mixed region (4) is interpolated according to the density. This is not true since it will be two fases. my_pT Pa s Viscosity as a function of pressure and ...

WebbProperties of Water and Steam” for industrial use, called IAPWS-IF97 for short. The formulation IAPWS-IF97 replaced the previous industrial formulation IFC-67 published in 1967. After the adoption of IAPWS-IF97 in 1997, further so-called backward equations were developed. These studies were coordinated by the IAPWS Task Group on … flower coloring sheets hard
