Convective Heat Transfer Coefficient
Convective heat transfer coefficient, abbreviated as \(h_c\), also called film coefficient or film effectiveness, is a porportional constant between heat flux and force from the flow of heat, this also depends on the type of fluid and fluid velocity.

\(\large{ h_c }\) = heat transfer coefficient | \(\large{\frac{Btu}{hr-ft^2-F}}\) | \(\large{\frac{W}{m^2-K}}\) |
\(\large{ Q }\) = amount of heat transfered area of the surface | \(\large{\frac{Btu}{hr}}\) | \(\large{ W }\) |
\(\large{ \Delta T }\) = temperature differential between solid surface and surrounding fluid area | \(\large{ F }\) | \(\large{ K }\) |
