# Convective Heat Transfer Coefficient

Convective heat transfer coefficient ( \(h_c\) ) (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.

### Convective Heat Transfer Coefficient Formula

\(\large{ h_c = \frac { Q } { \Delta T } }\)

Where:

\(\large{ h_c }\) = heat transfer coefficient

\(\large{ Q }\) = amount of heat transfered area of the surface

\(\large{ \Delta T }\) = temperature differential between solid surface and surrounding fluid area
