# Convective Heat Transfer

Convective heat transfer, abbreviated as \(\dot {Q}\), is the transfer of heat by bulk movement and mixing from one place to another of liquids or gasses.

### Convective Heat Transfer Formula

\(\large{ \dot {Q} = h_c \; A \; \left( T_s \;-\; T_a \right) }\)

Where:

\(\large{ \dot {Q} }\) = heat transfer per unit time

\(\large{ A }\) = heat transfer area of the surface

\(\large{ h_c }\) = heat transfer coefficient

\(\large{ T_a }\) = air temperature

\(\large{ T_s }\) = surface temperature
