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
\(\large{ h_c = \frac { Q  }  { \Delta T }  }\)
Symbol	English	Metric
\(\large{ h_c }\)  = 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	\(\large{ F }\)	\(\large{ K }\)
