K value of teflon
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)) WebWear factor (K): Used to quantify wear resistance Lower Value = Better Wear Resistance! K = W/(F x V x T) K = Wear Factor: (in3-min/ft-lb-hr) · 10-10 or (mm3/N-m) · 10-8 W = Volume wear: in3 or mm3 F = Force: lb or N V = Velocity: ft/min or m/sec T = Elapsed time: hr or sec 100 Hour Test!
