3. Water at an average bulk temperature of 80 F flows inside a horizontal smooth tube with wall temperature maintained at 180 F. The tube length is 6 ft and the diameter is 0.5 in. The flow velocity is 0.4 ft/s. Calculate the heat transfer rate. For water, c = 1 Btu/lb-F and k = 4.27 Btu- in/hr-ft2-F. *

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 =

5. Steam condensing on the outer surface of a thin-walled circular tube of 50 mm diameter and 6 m length maintains a uniform surface temperature of 100 C. Water flows through the tube at a rate of m= 0.25 kg/s, and its inlet and outlet temperatures are Tmi = 15 C and Tmo = 57C. What is the average convection coefficient associated with the water flow? Data: Pvater = 1000 kg/m³ ; c, = 4.2 kJ/kg-K.
