thermal conductance
Definition from Wiktionary, the free dictionary
English[edit]
Noun[edit]
thermal conductance (plural thermal conductances)
Usage notes[edit]
The heat (thermal energy) flow P_{th} through a given body depends on the thermal conductance C_{th} of that body, and the temperature difference ΔT over it, and follows the formula:
Thus, the higher the conductance, the higher the heat flow. The unit of thermal conductance in SI system of units is W·K^{−1}. For the special case of an ideal plate with area A, thickness d and thermal conductivity λ, the thermal conductance of the plate is:
The multiplicative inverse of thermal conductance is thermal resistance, denoted as R_{th}.
