Abstract

Steam tables for practical industrial use are presented that were calculated using the international standard for the thermodynamic properties of water and steam, the IAPWS-IF97 formulation, and the IAPWS industrial standards for the transport and other properties. In addition, the complete set of equations of IAPWS-IF97 is presented including all supplementary backward equations for fast calculations of heat cycles, boilers, and steam turbines. These steam tables contain the following features: Formulas to calculate from IAPWS-IF97 arbitrary partial derivatives of the eight most important properties, which is very helpful in non-stationary process modelling. The uncertainty values of IAPWS-IF97 regarding the most important properties are included.
