| Abstract: | A flow apparatus for measuring heat capacities of liquid and liquid mixtures at the pressure up to 12 MPa, at the temperatures from 260 K to 470 K was developed. It was verified by measuring specific heat capacities of water in liquid. And its relative uncertain amounts is within 0.6% for water by comparing the experimental results with the literature values. This research is essential for measuring heat capacities of liquid and liquid mixtures. |
