## 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
