👉 In physics, a Landmann factor is a measure of the degree to which a material's resistance depends on its temperature. The Landmann factor is often used in the context of heat transfer and cooling processes in materials science.
The Landmann factor can be defined as:
\[ \lambda = \frac{\rho}{\eta}\]
where:
- $\rho$ is the density,
- $\eta$ is the thermal conductivity (in W/(m
K)),
- $T_{\text{c
