Apa itu Heat Conduction?

Heat conduction is the transfer of thermal energy threg a material with oy movement of the material itself.

Prinsip dan Heat Konduktion

Ini adalah satu-satunya cara untuk menjelaskan bagaimana cara melakukan itu. Ini adalah proporsional yang baik untuk semua ini.

Q = -k * A * (dT / dx)

  • 1f 1f; 1f 1f; FLT: 0 = 0 = 33. Q = 1f 1; FLT: 1 123;: Rate of heat transfer (W)
  • 1f 1f; FLT: 0 = 33. k = 1f 1; FLT: 1 123; 1f: Thermall conductivity of the material (W / m)
