Question:

Air (c_p = 1007 J/kg · K) enters a 17-cm-diameter and 4-m-long tube at 65°C at a rate of 0.08 kg/s and leaves at 15°C. The tube is observed to be nearly isothermal at 5°C. The average convection heat transfer coefficient is
(a) 24.5 W/m² · K

(b) 46.2 W/m² · K

(d) 67.6 W/m² · K

(e) 90.7 W/m² · K
