Thermal expansion coefficient β = (1/ν) (∂ν/∂T)p of liquid water as a function of pressure and temperature. (β in 10−3/K.) Table 10. For most gases over a wide range of temperature and pressure, Pr is approximately constant. Therefore, it can be used to determine the thermal conductivity of gases at high temperatures, where it is difficult to measure experimentally due to the formation of convection currents. Typical values for Pr are: • 0.003 for molten potassium at 975 K sebaceous cyst characteristics https://tuttlefilms.com
