4 lis 2012 · Thermal resistance is the ability of a material to resist flow of heat. Thermal resistivity is the reciprocal of thermal conductivity and can be expressed as. r = 1 / k (1) where. r = thermal resistivity (moC/W, hr ft2 oF/ (Btu in)) k = thermal conductivity (W/ (moC), Btu in/ (hr ft2 oF))
