摘要: In this paper the results of volumetric, isobaric heat capacity, and thermal conductivity measurements in liquid region a round-robin sample Krytox GPL102 oil are reported. The presented here part worldwide program for determination transport properties perfluoropolyether oil. Density was measured from (278.15 to 398.15) K up 120 MPa, whereas capacity were performed at atmospheric pressure (278.00 398.14) (278.77 323.29) K, respectively. represented within 0.0003 g·cm–3, 0.005 J·g–1·K–1, 2 mW·m–1·K–1 by using different correlation equations. provided Tammann–Tait equation state with seven parameters used determine expansivities, bulk modulus, isothermal compressibilities. Finally, temperature dependence diffusivities also analyzed.
