A stainless steel pin fin 5 cm long, 6 mm OD, extends from a flat plate into a 175 m/s
A stainless steel pin fin 5 cm long, 6 mm OD, extends from a flat plate into a 175 m/s air stream as shown in the accompanying sketch.(a) Estimate the average heat transfer coefficient between air and the fin.(b) Estimate the temperature at the end of the fin.(c) Estimate the rate of heat flow from the fin.GIVENA stainless steel pin fin in an air streamPin length (L) = 5 cm = 0.05 mPin diameter (D) = 6 mm = 0.006 mAir velocity (U??) = 175 m/sASSUMPTIONSSteady stateAir approaching the fin has negligible turbulenceRadiative heat transfer is negligibleSteel is type 304Steel properties areuniform
