SUPPLEMENTARY MEASUREMENTS OF THE (PRESSURE, DENSITY, TEMPERATURE) RELATION OF CARBON-DIOXIDE IN THE HOMOGENEOUS REGION AT TEMPERATURES FROM 220-K TO 360-K AND PRESSURES UP TO 13-MPA

This paper presents accurate (p, ρ, T) measurements on pure carbon dioxide in the temperature range from 220 K to 360 K at pressures up to 13 MPa. The measurements (264 values) have been carried out to supplement our earlier comprehensive measurements of Duschek et al. in the pressure range up to 9 MPa. The new measurements have been performed on 13 isotherms in the pressure range from 9 MPa to 13 MPa and on five supercritical isotherms in the pressure range from 1 MPa to 13 MPa. The total uncertainty of the measurements is <(|1.5·10-4·ρ| to |4·10-4·ρ|). Comparisons with the experimental results of previous workers are presented. © 1992 Academic Press Limited All rights reserved.
