How to get thermal conductivity
WebThermal conductivity of Concrete is 0.5 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction. Note that Fourier’s law applies for all matter ... WebYou can analyze the flow of thermal energy through multiple materials in series by using the thermal resistance ( en.wikipedia.org/wiki/Thermal_resistance ). However, you need to identify the dominant mode of heat transfer. In copper, it's conduction; with a water flow, however, it's likely not conduction but convection.
