Where to get thermal conductivity data?

pswpswpsw · June 18, 2014, 06:21

Hi guys,

I need to get a formula for the thermal conductivity for helium around the temperature range 300K ~ 800K. But I searched the internet without any findings. Can anyone help?

Best,
Shaowu

If you need a simple equation, just use a cubic fit for the data.
