I am looking for a computer program that will calculate various thermophysical properties for cryogenic Helium-4 (gas and liquid-I) given the temperature and pressure. The temperature range of interest is from about 2 K to 70 K, and the pressure range from 0.1 to 20 atm. The thermophysical properties of most interest are the density, thermal conductivity, viscosity, thermal diffusivity, Prandtl number, enthalpy, entropy, heat capacity (@ const. V and P), and the velocity of sound. Also of interest would be the properties in the two phase region. I have a set of tables produced in 1972 by R.D. McCarty, which tabulate the above data. However, I'd like to save time and see if somebody has already coded this data or newer data. Any help out there? Thank you in advance, Jon Noring
