A plane wall surface at 200°C is to be cooled with aluminum pin fins of parabolic profile with blunt tips. Each fin has a length of 25 mm and a base diameter of 4 mm. The fins are exposed to an ambient air condition of 25°C and the heat transfer coefficient is 45 W/m2·K. If the thermal conductivity of the fins is 230 W/m·K, determine the heat transfer rate from a single fin and the increase in the rate of heat transfer per square meter surface area as a result of attaching fins. Assume there are 100 fins per square meter surface area.

Question
A plane wall surface at 200°C is to be cooled with
aluminum pin fins of parabolic profile with blunt tips. Each
fin has a length of 25 mm and a base diameter of 4 mm.
The fins are exposed to an ambient air condition of 25°C
and the heat transfer coefficient is 45 W/m2·K. If the thermal
conductivity of the fins is 230 W/m·K, determine the heat
transfer rate from a single fin and the increase in the rate
of heat transfer per square meter surface area as a result of
attaching fins. Assume there are 100 fins per square meter
surface area.
