    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:

    q = hc A dT

    where

    hc is convective heat transfer coefficient of the process (W / (m2K) or W / (m2oC q

    A is the heat transfer area of the surface (m2, ft2)

    hc = convective heat transfer coefficient of the process (W / (m2K) or W / (m2oC), Btu / (ft2 h oF)) q is heat transferred per unit time (W, Btu/hr) dT is the temperature difference between the surface and the bulk fluid (K or oC, F)
