| Abstract: | The viscosity and density of 1,1,1,2,3,3,3-Heptafiuoropropane(HFC-227ea) were reported at temperatures from 243.15 K to 363.15 K and at pressures up to 11.49 MPa.The measurements were performed simultaneously using a vibrating-wire instrument operated in the forced mode of oscillation.The overall uncertainties of these results are±2.0%in viscosity and±0.2%in density. Correlations for both the viscosity and the density are presented.The average absolute deviation and the maximum absolute deviation of the viscosity measurements from the correlation are 0.71% and 2.02%respectively,and for density are 0.05%and 0.15%,respectively.Comparisons between measurements of this work and literatures are presented. |
