WebIt measures the rate of transfer of heat of a material from the hot side to the cold side. It has the SI unit of m²/s. Thermal diffusivity is usually denoted α but a , κ , K , and D are also used. The formula is: α = k / ( ρ c p ) where. k is thermal conductivity (W/ (m·K)) ρ is density (kg/m³) c p is specific heat capacity (J/ (kg·K)) WebTorque value is defined as the measured ability of a rotating element to overcome turning resistance. FluoroKote#1® will reduce the torque significantly by lowering one of its components, the K factor, or torque coefficient. The fluoropolymer used in the final coat of FluoroKote#1® has a kinetic friction coefficient of 0.06-0.08. dare county solid waste
