Heat Transfer by Covection

Written by Jerry Ratzlaff on . Posted in Thermodynamics

heat conductionHeat transfer by convection ( \(Q_c\) ) (also called convection heat transfer or convective heat transfer) is the flow of heat from one place to another by the movement of fluids (liquids or gasses).

Heat Transfer by Convection 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
