Carbon dioxide - Thermal Conductivity vs. Temperature and Pressure
Online calculator, figures and table showing thermal conductivity of carbon dioxide, CO2, at temperatures ranging from -50 to 775 °C (-50 to 1400 °F) at atmospheric and higher pressure - Imperial and SI Units.
Thermal conductivity is a material property that describes ability to conduct heat . Thermal conductivity can be defined as
" the quantity of heat transmitted through a unit thickness of a material - in a direction normal to a surface of unit area - due to a unit temperature gradient under steady state conditions".
Thermal conductivity most common units are W/(m K) in the SI system and Btu/(h ft °F) in the Imperial system.
Tabulated values and thermal conductivity units conversion are given below the figures.
