Equivalencia métrica del sistema inglés en tamaños de tuberías
La intención de las autoridades estadounidenses es de eventualmente convertir
todas las mediciones al sistema métrico. Las siguientes equivalencias métricas
han sido obtenidas del sistema convencional inglés. Estas equivalencias van de
acuerdo con las normas Británicas y Alemanas.

Fuente: Las tablas A-4 a A-8 fueron generadas utilizando el programa para resolver ecuaciones de ingeniería (EES) desarrollado por S. 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.

Fuente: Las tablas A-11 a A-13 se generaron utilizando el programa para resolver ecuaciones de ingeniería (EES) desarrollado por S. A. Klein y F. L. Alvarado. La
rutina utilizada en los cálculos es la R134a, la cual está basada en la ecuación fundamental de estado desarrollada por R. Tillner-Roth y H. D. Baehr, “An
Internacional Standard Formulation for the Thermodynamic Properties de 1,1,1,2-Tetrafluoretano (HFC-134a) for temperatures from 170 K to 455 K and pressures
up to 70 MPa”, J. Phys. Chem, Ref. Data, vol. 23, núm. 5, 1994. Los valores de entalpía y entropía para el líquido saturado son cero a –40°C (y –40°F).

Fuente: Los valores han sido obtenidos de varios manuales y otras fuentes, o se han calculado. El contenido de agua y los datos de punto de congelación
para alimentos provienen del ASHRAE, Handbook of Fundamentals, versión I-P, Atlanta, Georgia, American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc., 1993, Capítulo 30, Tabla 1. El punto de congelación es la temperatura a la que comienza la congelación para frutas y verduras,
así como la temperatura promedio de congelación para otros alimentos.

Fuente: Las tablas A-4E a A-8E fueron generadas utilizando el programa para resolver ecuaciones de ingeniería (EES) desarrollado por S. 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.

Fuente: Las tablas A-11E a A-13E se generaron utilizando el programa para resolver ecuaciones de ingeniería (EES) desarrollado por S. A. Klein y
F. L. Alvarado. La rutina utilizada en los cálculos es el R134a, el cual está basado en la ecuación fundamental de estado desarrollada por R. Tillner-Roth y
H. D. Baehr, “An International Standard Formulation for the Thermodynamic Properties de 1,1,1,2-Tetrafluoretano (HFC-134a) for temperatures from
170 K to 455 K and pressures up to 70 MPa”, J. Phys. Chem, Ref. Data, vol. 23, núm. 5, 1994. Los valores de entalpía y entropía para el líquido
saturado son cero a –40°C (y –40°F).
