Heat Conduction

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Heat conduction (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.

  • Abbreviated as COND

formula

\(Q =  \frac { kA \Delta T  t }   {d}   \)

\(Q =  \frac { kA  \left(  T_h \;-\; T_c  \right) t }   {d}   \)

Where:

\(Q\) = heat conduction or transfer

\(k\) = thermal conductivity

\(A\) = cross sectional area  

\(\Delta T\) = temperature differential

\(T_h\) = higher temperature

\(T_c\) = cooler temperature

\(t\) = time taken

\(d\) = thickness of the material
