# Convective Heat Transfer Coefficient

## 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

\(h_c = \frac { Q } { \Delta T } \) \(heat \; transfer \; coefficient \;=\; \frac { amount \; of \; heat \; transfered \; area } { temperature \; differential } \)

Where:

\(h_c \) = heat transfer coefficient

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

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