Webb17 dec. 2012 · I prefer IAPWS 1995 over IF-97 cause IAPWS 97 is a reduced version for industrial use (I presume you refer to that version), it has been conceived to be faster but in my tests with Prode and Chemicalogic they run at about the same speed, with the advantage for IAPWS 1995 to be more accurate. WebbThe valid range of calculations for thermodynamic properties is defined by the IAPWS (International Association for the Properties of Water and Steam) as shown on Figure 1, together with the correspondent division of regions.
