Abstract
Heat conductivity for a Novec 7100 fluid sample was measured with a method of coaxial cylinders. Experiments were performed in the temperature range 350 - 385 K and pressure range 0.12 - 0.21 MPa. The error for experimental data on heat conductivity is about 1.5 - 2.5 %, The error in measuring temperature and pressure was less than 0.05 K and 4 kPa, correspondingly. The general equation for calculating the heat conductivity as a function of pressure and temperature was formulated. The heat conductivity was defined for the ideal gas state. A previously developed approach was tested in application for a single-measurement prognosis of heat conductivity.
