Heat Conduction

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Heat conduction, abbreviated as $$Q_c$$, by conduction is one of three types of to heat transfer: conduction, convection and radiation.  It is the flow of heat between two objects having different temperatures that are in contact with each other.

Heat Conduction Formula

(Eq. 1)  $$\large{ Q_c = \frac { k \; A \; \Delta T \; t } {d} }$$

(Eq. 2)  $$\large{ Q_c = \frac { k \; A \; \left( T_h \;-\; T_c \right) \; t } {d} }$$

Where:

$$\large{ Q_c }$$ = heat transfer by conduction

$$\large{ A }$$ = area cross section

$$\large{ T_c }$$ = cooler temperature

$$\large{ T_h }$$ = higher temperature

$$\large{ \Delta T }$$ = temperature differential

$$\large{ t }$$ = time taken

$$\large{ k }$$ = thermal conductivity

$$\large{ d }$$ = thickness of the material
