Dry, compressed air at Tm,i = 75C, p = 10 atm, with a mass flow rate of = 0.001 kg/s, enters a 30-mmdiameter, 5-m-long tube whose surface is at Ts = 25C. Determine the thermal entry length, the mean temperature of the air at the tube outlet, the rate of heat transfer from the air to the tube wall, and the power required to flow the air through the tube. For these conditions the fully developed heat transfer coefficient is h = 3.58 W/m2.K. (8.12 a)
