Heat Transfer Conduction Calculator

The conduction calculator deals with the type of heat transfer between substances that are in direct contact with each other. Heat exchange by conduction can be utilized to show heat loss through a barrier. For a wall of steady thickness, the rate of heat loss is given by:

\[ Q = \frac{KA(T_{hot}{-}T_{cold})}{d} \]

\(Q\) = Conduction heat transfer (W)
\(K\) = Materials thermal conductivity (W/mK)
\(A\) = Cross sectional area ()
\(T_{Hot}\) = Higher temperature (°C)
\(T_{Cold}\) = Colder temperature (°C)
\(d\) = Material thickness (m)
