Convective Heat Transfer

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

Convective Heat Transfer Formula

\(\dot {Q} = h_c A \left( T_s \; - \; T_a  \right)    \)          \(heat \; transfer \;=\; heat \; transfer \; coefficient \;\;x\;\; hear \; transfer \; area \; \left( \;  surface \; temperature \; - \; air \;temperature  \; \right)    \)

Where:

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

\(A \) = heat transfer area of the surface

\( h_c\) = heat transfer coefficient

\(T_a \) = air temperature

\(T_s \) = surface temperature
