“…The speed of sound in liquids CF 3 CF 2 CHCl 2 and CClF 2 CF 2 CHClF, calculated by above equation, reproduced the experimental data (apart from that measured at 343.15 K) with a maximum deviation AE 0.25%. Recently, Padilla-Victoria et al 19 correlated the speed of sound for the liquid n-alkanes C 5 to C 40 [see By combining the density, r, and sound velocity, u, the isentropic compressibility, k S , of the fluid can be calculated from Equation (13.3). The k S (T,P) for toluene and acetone calculated in this way have been plotted against pressure, P, in Figure 13.7.…”

“…Details of up to 2000 of these publications have been correlated and reviewed by many researchers including Oakley et al 12,13 (2003), Neruchev et al 14 (2005), Lemmon, 15 (2006) and Takagi and Wilhelm 16 (2010). In addition, the reviews of u(T,P) data of specialised substances such as alcohols or alkanes have been correlated by Queimada et al 17 (2006), Liang et al 18 (2012) and by Padilla-Victoria et al 19 (2013).…”

The pressure-volume (density)-temperature (P-r-T) surface of a fluid presents the basic thermodynamic properties for investigating the behaviour of fluids. The isothermal compressibility, k T , and isentropic (adiabatic) compressibility, k S , of a fluid are defined as:(13:1)where r refers to the specific molar volume, P to pressure, T to temperature and S to entropy. The pioneering studies on the P-r-T relationships for various compounds were conducted by Bridgman, 1,2 Gibson and Kincaid 3,4 and many colleagues in the early 20th century. Today, the experimental P-r-T data of a large number of liquids and/or mixtures have been stored or published in a variety of styles. Examples include the databases of Volume Properties: Liquids, Solutions and Vapours Edited by Emmerich Wilhelm and Trevor M. Letcher
