1、Designation: D 4650 93 (Reapproved 2003)Standard Specification forNormal Butane Thermophysical Property Tables1This standard is issued under the fixed designation D 4650; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of
2、last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 The normal butane thermophysical property tables arefor use in the calculation of the pressure-volume-temperature(PVT
3、), thermodynamic, and transport properties of normalbutane for process design and operations. Tables are providedfor gaseous and liquid normal butane at temperatures between135 and 600K at pressures to 70 MPa. These tables weredeveloped by the National Institute of Standards and Technol-ogy (formerl
4、y the National Bureau of Standards) upon culmi-nation of four years of effort in acquiring available physicalproperties data, performing experimental measurements, and informulating these tables for use in thermal computations.2. Sponsorship2.1 The preparation of the tables and supporting work wasdo
5、ne by the National Institute of Standards and Technology(NIST) under the sponsorship of the Gas Research Institute, theAmerican Gas Association, and the Standard Reference DataProgram of NIST.3. Applicability3.1 These tables apply directly only to pure gaseous andliquid normal butane. However, it is
6、 expected that they willfind substantial use in mathematical models and tables for thethermophysical properties of mixtures containing normal bu-tane, such as natural gas.4. Tables4.1 These thermophysical property tables2are:4.1.1 Thermophysical Properties of Coexisting Gaseous andLiquid Normal Buta
7、ne, in SI units (Table in Appendix I, pp.758760).34.1.2 Thermophysical Properties of Normal Butane, alongisobars, in SI units (Table in Appendix I, pp. 762793).34.2 These tables were produced by equations from a com-puter package, “NIST Thermophysical Properties of FluidsDatabase 12” (also designate
8、d MIPROPS) of the StandardReference Data Program of NIST.4A wide selection of units(SI units, engineering units, chemical units) are available withthis program.5. Additional Information5.1 These tables were originally published by the AmericanChemical Society and the American Institute of Physics fo
9、r theNational Institute of Standards and Technology in a compre-hensive report titled “Thermophysical Properties of Fluids. II.Methane, Ethane, Propane, Isobutane and Normal Butane.”5This report also contains the following:5.1.1 Properties and uncertainties data.5.1.2 Correlation equations for norma
10、l butane.5.1.3 Description of the research study culminating in thetables.5.1.4 References to properties data.5.1.5 Computational methods used.1This practice is under the jurisdiction of ASTM Committee D03 on GaseousFuels and is the direct responsibility of Subcommittee D03.08 on ThermophysicalPrope
