Ethane - Thermal Conductivity vs. Temperature and Pressure

Online calculator, figures and table showing thermal conductivity of ethane, C₂H₆, at varying temperature and 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"

The SI unit used for thermal conductivity is (W/m K), while a common Imperial unit is (Btu/h ft °F).
