چکیده انگلیسی
Saturated liquid densities and bubble point pressures for binary mixtures of 1,1,1,2-tetrafluoroethane (HFC134a)â+âpropane (HC290) were measured using a compact single-sinker densimeter. The temperature range was from 253 to 293 K and mole fractions of HFC134a were 0.105, 0.197, 0.331, 0.387, 0.536 and 0.557. The standard uncertainties were estimated to be less than 5 mK for temperature, 1âkPa for pressure, 0.003 for mole fraction, and 0.02% for density. The experimental results were reproduced by VNDS equation and our modified Rackett equation. The saturated pressures data were correlated by the PR-Soave-vdW equation. Good agreement between values of calculation and experiment were found.
