Air thermal k at low pressure

[JKEngineer]

Can anyone give me some leads or information on the thermal conductivity of air as a function of pressure for sub-atmospheric conditions?
All help appreciated!

See 10.12 of "The Properties of Gases and Liquids" by
Prausnitz and others, fifth edition.

Thanks for the suggestion. I will have to get to a library, the only Prausnitz I have is on phase equilibria. I think I used one edition of the book you suggested for a course about 25 years ago, but borrowed it from the library at my job at the time.

I haven't seen those tables however remembered that absolute (dynamic) viscosity, thermal conductivity, heat capacity and the Pr number don't change much over a wide pressure range. I have seen a copy of seven listed air physical properties at atmospheric pressures by The National Bureau of Standards (US) Circ. 564 (1955) between 100 K and 2500 K.

Here's another library reference (earlier edn. of one above?):
