Convective Heat Transfer Coefficient

Written by Jerry Ratzlaff on . Posted in Thermodynamics

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 \(\large{ F }\) \(\large{ K }\)
