Air at 60oC and 1 atm enters a smooth tube having a diameter of 2 cm and length of 10 cm. The air velocity is 40 m/s: 1- What constant heat flux must be applied at the tube surface to result in an air temperature rise of 5oC? 2- What average wall temperature would be necessary for this case?

Answer: (1) qs = 11841W/m2    (2) Tw = 97oC
