Thermal conductivity, thermal diffusivity, and R-value. As mentioned above, thermal conductivity tells us how fast (or how much) heat can transfer through a given material. A more formal definition would be the quantity of heat (Q) transmitted through a stationary material with a unit thickness (L) in a direction normal to a unit surface area (A) due to a temperature gradient . Equation () is the one-dimensional solution of Fourier’s law for a steady-state method.It allows the calculation of the thermal conductivity in W m −1 K −1, where q is the heat flow throughout the sample per unit area in W m −2, Q (Q = q
The affordable Hot Disk® TPS 1500 is the ideal thermal conductivity meter for testing building materials, insulation materials or any other type of large bulk samples. The TPS 1500 Thermal Conductivity range comprises 0.01 to 400 W/m/K, and the instrument handles temperatures from -100°C to 750°C.
Thermal conductivity, k, is thus defined as. k = Q * X / ((T H - T C) * A) The most popular units for thermal conductivity are Watt/meter Kelvin (W/mK). Thermal resistivity is simply defined as the reciprocal of thermal conductivity. An alternate expression for k can be made by using thermal resistance, R, of the material sample between the .
