ABSTRACT
Measurements of (p, rho, T) properties for compressed liquid propane have been obtained by means of a metal-bellows variable volumometer at temperatures from 340 to 400 K at pressures up to 200 MPa. The volume-fraction purity of the propane sample was 0.9999. The expanded uncertainties (k = 2) of temperature, pressure, and density measurements have been estimated to be less than 3 mK; 1.5 kPa (p7 MPa), 0.06% (7 MPap50 MPa), 0.1% (50 MPap150 MPa), and 0.2% (p150 MPa); and 0.11%, respectively. Four (p, rho , T) measurements at the same temperatures and pressures as literature values have been conducted for comparisons. In addition, vapor pressures were measured at temperatures from 280 to 369 K. Furthermore, comparisons of available equations of state with the present measurements are reported.
