Extracted text: Dry, compressed air at Tm,i whose surface is at T; = 25°C. Determine the thermal entry length, in m, the mean temperature of the air at the tube outlet, in K, the rate of heat transfer from the air to the tube wall, in W, and the power required to flow the air through the tube, in W. For these conditions the fully developed heat transfer coefficient is h = 3.58 W/m2-K. Evaluate the properties of air at 320 K 75°C, p = 10 atm, with a mass flow rate of m = 0.003 kg/s, enters a 32-mm-diameter, 5-m-long tube i Tmo = i K P = i q =
