Solve Problem 20.29 if the medium flowing past the tube in forced convection is water at 60°F.

Data From Problem 20.29

An electric light bulb rated at 60 W has a surface temperature of 145°C when cooled by atmospheric air at 25°C. The air flows past the bulb with a velocity of 0.5 m/s. The bulb can be modeled as a sphere with a diameter of 7.5 cm. Determine the heat transfer from the bulb by the mechanism of forced convection.
