# Heat Transfer Coefficient

Heat transfer coefficient, abbreviated as h, also called film coefficient or film effectiveness, is the convective heat transfer between a solid surface and the fluid around it.

\(\large{ h }\) = heat transfer coefficient | \(\large{\frac{Btu}{hr-ft^2-F}}\) | \(\large{\frac{W}{m^2-K}}\) |

\(\large{ Q" }\) = heat flux | \(\large{\frac{Btu}{hr-ft^2}}\) | \(\large{\frac{W}{m^2}}\) |

\(\large{ \Delta T }\) = temperature differential between the solid surface and surrounding area | \(\large{F}\) | \(\large{K}\) |
