CALCULATION OF THE THERMODYNAMIC PROPERTIES OF WATER USING THE IAPWS MODEL
Beginning 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. This new model, termed IAPWS-IF97, was adopted beginning in 1997, but an evaluation and changeover peri...
