Heat transfer by convection, abbreviated as CONVN, is the transfer of heat by air, water, or any other substance that passes over an object, the surface having a higher temperature than the one passing over it. This is one of four types of to heat transfer: mixing, conduction, convection and radiation.
Heat Convection formula
\(Q = h \; A \; \left( T_h - T_c \right) \)
\(Q\) = heat transfer by convection
\(h\) = heat transfer coefficient
\(A\) = cross sectional area
\(T_h\) = higher temperature
\(T_c\) = cooler temperature
