Deviation graphs comparing experimental speed of sound values, wexp, to speed of sound values calculated using REFPROP [6] mixture models that incorporate pure-fluid EOS [7–11] and fitted binary interaction parameters [12, 13], wcalc, as a function of wexp. Dashed lines represent the experimental uncertainty of the speed of sound data as a function of the speed of sound. The systems and molar compositions are (a) R-125/1234yf (0.33351/0.66649), (b) R-125/1234yf (0.66643/0.33357), (c) R-1234yf/152a (0.33342/0.66658), (d) R-1234yf/152a (0.66526/0.33474), (e) R-1234ze(E)/227ea (0.33265/0.66735), and (f) R-1234ze(E)/227ea (0.66803/0.33197). Comparisons are shown at temperatures, Inline graphic, 230 K; Inline graphic, 235 K; Inline graphic, 240 K; Inline graphic, 245 K; Inline graphic, 250 K; Inline graphic, 255 K; Inline graphic, 260 K; Inline graphic, 265 K; Inline graphic, 270 K; Inline graphic, 275 K; Inline graphic, 280 K; Inline graphic, 285 K; Inline graphic, 290 K; Inline graphic, 295 K; Inline graphic, 300 K; Inline graphic, 305 K; Inline graphic, 310 K; Inline graphic, 315 K; Inline graphic, 320 K; Inline graphic, 325 K; Inline graphic, 330 K; Inline graphic, 335 K; Inline graphic, 340 K; and Inline graphic, 345 K (Color figure online)
