# Heat Transfer by Convection

Heat transfer by convection, abbrteviated as \(Q_c\), 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) \(\large{ Q_c = \frac { k \; A \; \Delta T \; t } {d} }\)

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

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
