Heat Transfer by Conduction

Written by Jerry Ratzlaff on . Posted in Thermodynamics

heat conductionHeat transfer by conduction ( \(Q_c\) ) (also called heat conduction, heat radiation, or heat transfer) is the flow of heat between two objects having different temperatures that are in contact with each other.

Heat Transfer by Conduction Formula

(Eq. 1)  \(\large{ Q_c =  \frac { kA \Delta T  t }   {d}   }\)         

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

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
