Web5.1.1.3 Thermal Conductivity. The thermal conductivity coefficient k is a material parameter depending on temperature, physical properties of the material, water content, and the pressure on the material [3]. The coefficient k is measured in watts per meter Kelvin (or degree) (W/mK). In general, a material with a large k is a good heat ... WebSep 9, 2024 · The ratio of the rate of heat flow per unit area to the negative of the temperature gradient is called the thermal conductivity of the material: (4.3.1) d Q d t = − K A d T d x. I am using the symbol K for thermal conductivity. Other symbols often seen are k or λ. Its SI unit is W m −1 K −1.
