The thermal conductivity of a specific material is highly dependent on a number of factors. "bulk" refers to a group of nanotubes either arranged or disordered, for a single nanotube, see "carbon nanotube, single". Since the thermal conductivity of air is very much smaller than that of water or solid matter, a high air content (or low water content) corresponds to a low thermal conductivity.

Errata: Contrary to what they say the formula of Bonales and Sanz cannot be fitted to their data and also it is not consistent with the results of Choi and Okos since their formula is a typo and also Choi and Okos did not cook up a linear function to start with. For the sake of simplicity the conductivities that are found by that method in all of its variations are noted as L conductivities, those that are found by radial measurements of the sort are noted as R conductivities, and those that are found from periodic or transient heat flow are distinguished as P conductivities. The heat transfer conduction calculator below is simple to use. This chart gives the thermal conductivity of gases as a function of temperature. Generally, the coefficient of thermal conductivity λ of a metal equals the sum of lattice (phonon) λ ph, and electron λ e components, λ = λ e + λ ph; at ordinary temperatures, as a rule, λ e >>λ ph. We design, develop and supply high quality, high value thermal systems to automotive OEMs on four continents. Figure 1. Robertson says that Rockport-1 has 25% Quartz and Rockport-2 has 33% Quartz and he usually talks in volume percent. Inst. The air gap can be replaced by an inert gas such as Ar or Kr having higher thermal conductivity We can also coat the glass with so called “high emissivity” coatings which are Various conductivities less than 0.4 w m−1 K−1.
