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.

 

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
