There is a circular steel tube 6 cm in diameter and 20 m long, in which water circulates with a flow of 0.5 kg/s at a temperature of 30C, around the tube there is hot air at a speed of 5 m/s with a temperature of 100c. Determine the outlet temperature of the water at the end of the tube and the heat transferred to the surface of the tube if it has a temperature of 60C
