International thermodynamic tables of the fluid state. 5. Methane

Abstract

The major part of this book is concerned with the preparation of an equation of state from the available experimental data, and with the density integrals resulting from it, which form the various X/sub 2/(p,T). The only published equation of state that takes account of all the new data is that by Goodwin, which was modified. The two equations are discussed. The tables presented give the volume, entropy, enthalpy, isobaric heat capacity, compression factor, fugacity/pressure ratio, Joule-Thomson coefficient, ratio of the heat capacities and speed of sound as functions of pressure and temperature; and the pressure, entropy, internal energy and isochoric heat capacity as functions of density and temperature for the gas and liquid states from 0.025 MPa to 1000 MPa at temperatures from 95 K to 470 K, and from 0.025 MPa to 40 MPa, 470 K to 620 K. Zero pressure tables are given, as are tables of the properties of the fluid phases along the saturation curve and the melting curve. 15 figures, 10 tables. (DP)
