A. Klein y F. L. Alvarado. La rutina utilizada en los cálculos es la altamente precisa Steam_IAPWS, que incorpora la Formulación 1995 para las Propiedades Termodinámicas de la Sustancia Agua Ordinaria para Uso Científico y General, editada por The International Association for the Properties of Water and Steam (IAPWS). Esta formulación reemplaza a la formulación de 1984 de Haar, Gallagher y Kell (NBS/NRC Steam Tables, Hemisphere Publishing Co., 1984), la cual está también disponible en EES como la rutina STEAM. La nueva formulación se basa en las correlaciones de Saul y Wagner (J. Phys. Chem. Ref. Data, 16, 893, 1987) con modificaciones para ajustarla a la Escala Internacional de Temperaturas de 1990. Las modificaciones están descritas por Wagner y Pruss (J. Phys. Chem. Ref. Data, 22, 783, 1993). Las propiedades del hielo están basadas en Hyland y Wexler, “Formulations for the Thermodynamic Properties of the Saturated Phases of H2O from 173.15 K a 473.15 K”, ASHRAE Trans., Part 2A, Paper 2793, 1983. 18Appendix_01 ITALICAS.qxd 915 7/12/11 14:26:00 916 TABLAS DE PROPIEDADES, FIGURAS Y DIAGRAMAS (UNIDADES SI) TABLA A-5 Agua saturada.

A. Klein y F. L. Alvarado. La rutina utilizada en los cálculos es la altamente precisa Steam_IAPWS, que incorpora la Formulación 1995 para las Propiedades Termodinámicas de la Sustancia Agua Ordinaria para Uso Científico y General, editada por The International Association for the Properties of Water and Steam (IAPWS). Esta formulación reemplaza a la de 1984 de Haar, Gallagher y Kell (NBS/NRC Steam Tables, Hemisphere Publishing Co., 1984), la cual está también disponible en EES como la rutina STEAM. La nueva formulación se basa en las correlaciones de Saul y Wagner (J. Phys. Chem. Ref. Data, 16, 893, 1987) con modificaciones para ajustarla a la Escala Internacional de Temperaturas de 1990. Las modificaciones están descritas por Wagner y Pruss (J. Phys. Chem. Ref. Data, 22, 783, 1993). Las propiedades del hielo están basadas en Hyland y Wexler, “Formulations for the Thermodynamic Properties of the Saturated Phases of H2O from 173.15 K a 473.15 K”, ASHRAE Trans., Part 2A, Paper 2793, 1983. 19Appendix_02 ITALICAS.qxd 965 7/12/11 14:26:52 966 TABLAS DE PROPIEDADES, FIGURAS Y DIAGRAMAS (UNIDADES INGLESAS) TABLA A-5E Agua saturada.
