Convection is transfer of heat between a solid and a moving fluid. Boiling or condensing processes are example for convection processes.
The formula for convection is:
<span>q = hc A dT</span>
where
<span>hc is convective heat transfer coefficient of the process (W/(m2K) or W/(m2oC <span>q
</span>A<span> is the heat transfer area of the surface (m2, ft2)
</span><span>hc </span><span>= convective heat transfer coefficient of the process (W/(m2K) or W/(m2oC), <span>Btu/(ft2 h oF)</span>)</span><span>q is heat transferred per unit time (W, Btu/hr)</span>dT is the <span>temperature difference between the surface and the bulk fluid (K or oC, F)</span>
