Thermophysical properties of gases and liquids

[misbah_zuheb]

Hi,

I am looking for the thermophysical (viscosity, thermal conductivity, diffusivity, linear expansion, dansity) values of gases and liquids at various pressure.

Can anyone tell me any useful resource of finding this data.


Thanks
Misbah

This one seems to be pretty popular.

If you need something more versatile, you should consider purchasing NIST REFPROPS.
