The new model is oriented toward facilitating calculations employing computers, improving accuracy, and improving consistency among the model's limiting regions as well as contributing towards improved process design and simulation. The latter model had been used for 30 years for the calculation of thermodynamic properties of water for industrial, scientific, and academic applications. Was recommended before replacing the current model which had been developed in the 1960's (IFC-67).
This new model, termed IAPWS-IF97, was adopted beginning in 1997, but an evaluation and changeover period 2ġDepartment of Chemical Engineering, Engineering Faculty, Universidad de Antofagasta, Antofagasta, Chile,ĢDepartment of Chemistry, Basic Sciences Faculty, Universidad de Antofagasta, Antofagasta, Chile,īeginning in 2000 the International Association for the Properties of Water and Steam (IAPWS) recommended the use of a new model for calculation of the thermodynamic properties of water and steam.

At the time, that question compelled me to answer in a way I didn't like, namely "I'll think about it, and I hope I'll have the answer by the next time we meet.
2-more than 20 years have gone by, and I am still waiting for a more intelligent question from one of my students. Gioia of the University of Naples) once asked me a question which I have used here as Example 4. I taught chemical engineering thermodynamics for about ten years at the University of Naples in the 1960s, and I still remember the awkwardness that I felt about any textbook I chose to consider-all of them seemed to be vague at best, and the standard of logical rigor seemed immensely inferior to what I could find in books on such other of the students in my first class subjects as calculus and fluid mechanics. Jonathan Swift This book emerges from a long story of teaching. If a Writer would know how to behave himself with relation to Posterity let him consider in old Books, what he finds, that he is glad to know and what Omissions he most laments.
