Air (c p = 1007 J/kg K) enters a 17cmdiameter and 4mlong tube at 65C at
Question:
Air (c_{p} = 1007 J/kg · K) enters a 17cmdiameter and 4mlong 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/m^{2} · K
(b) 46.2 W/m^{2} · K
(c) 53.9 W/m^{2} · K
(d) 67.6 W/m^{2} · K
(e) 90.7 W/m^{2} · K
