“…This iterative approach consists initially in estimating the variation of density p over a small interval A P considering the quantity a$T/Cp: to be constant, following Denielou et al [29] and deducing from this by derivation the coefficient a p ( T ) at P + A P . The values obtained for Downloaded by [University of California, San Diego] at 14: 25 17 November 2014 p ( T ) and a p ( T ) at pressure P + A P are then corrected by recalculating the value of p at P + A P using Equation ( 6 ) in which the behaviour of the coefficient a p with pressure is interpolated linearly over the interval from the known values at P and the estimated values at P+ A P . During this integration, the heat capacity C p is assimilated to a constant.…”

“…The speed of sound has already been estimated by correspondingstates models [7][8][9][42][43][44][45][46][47][48], although in most of these studies only simple fluids, such as liquefied gases, refrigerants, and hydrocarbons with chain lengths smaller than n-octane were considered.…”

“…In the first one, compressibility factors are directly obtained from the model and other properties, such as the speed of sound, are obtained through thermodynamic relations [7][8][9]. The second approach is to obtain directly the speed of sound through the expansion of the reduced speed of sound in the Pitzer acentric factor (Eqs.…”
