Heat Conduction

Written by Jerry Ratzlaff on . Posted in Thermodynamics

heat conductionHeat conduction ( \(COND\) ) (one of three ways to heat transfer: conduction, convection and radiation) is the flow of heat between two objects having different temperatures that are in contact with each other.

Heat Conduction Formula

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

(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
