A0.4-w cylindrical electronic component with diameter 0.3 cm and length 1.8 cm and mounted on a circuit board is cooled by air flowing across it at a velocity of 234.00 m/min. if the air temperature is 35°c, determine the surface temperature of the component in °c. for air properties evaluations assume a film temperature of 50°c. the properties of air at 1 atm and at this temperature are k = 0.02735 w/m·°c, ν = 1.798 × 10−5 m2/s, and pr = 0.7228.
