Purpose: Purpose of this paper is to report on the development of a new density measure- ment cell. Design/methodology/approach: Measurement cell based on Archimedean principle and consisting of induction furnace and a high/precision balance was applied for measurement of tin, silver and copper density. Findings: It was found that new cell is suitable for high temperature measurement of liquid metals density at temperatures from 700 to 1520°C. Measurement results are in a good agreement with the literature values. Density deviates by 0.5-1% depending on the metal. Research limitations/implications: Accuracy of the density measurement decreases at temperatures below 700°C due to oxidation of the melt surface. More accurate data on thermal expansion coefficient for sinker material is required. Practical implications: Experiments showed applicability of the new measurement cell. Archimedean principle is among the most sensitive density measurement techniques. New cell will be further used for measurement of iron-based alloys. Problems of measurements are discussed. Originality/value: Paper describes application of the known density measurement technique. The paper is of interest for the material scientists working with high-temperature thermophysical properties measurements and users of thermophysical properties data.

The computation of power cycles employing carbon dioxide as working fluid and extending down to the critical region requires the knowledge of the thermodynamic properties of CO2 within a wide range of pressures and temperatures. Available data are recognized to be insufficient or insufficiently accurate chiefly in the vicinity of the critical dome. Newly published density and specific heat measurements are employed to compute thermodynamic functions at temperatures between 0 and 50 deg C, where the need of better data is more urgent. Methods for the computation of thermal properties from density measurement in the low and in the high temperature range are presented and discussed. Results are reported of the computation of entropy and enthalpy of CO2 in the range 150–750 deg C and 40–600 atm. The probable precision of the tables is inferred from an error analysis based on the generation, by means of a computer program of a set of pseudoexperimental points which, treated as actual measurements, yield useful information about the accuracy of the calculation procedure.
