A counterflow, concentric tube heat exchanger is designed to heat water from 22 to 80 deg Cusing hot oil.which is supplied to the annulus at 162 deg C and discharged at 140 deg C. The thin-walled inner tube has a diameter of Di-22 mm and the overall heat transfer coefficient is 500 W/m2. K. The design condition calls for a total heat transfer rate of 3200 W. What is the length of the heat exchanger?

10.1 In a heat exchanger, as shown in the accompanying figure, air flows over brass tubes of 1.8-cm 1D and 2.1-cm OD containing steam. The convection heat transfer coefficients on the air and steam sides of the tubes are , respectively. Calculate the overall heal transfer coefficient for the heal exchanger (a) based on the inner tube area and (b) based on the outer tube area.
Mot water is used to heat air in a double-pipe heat exchanger as shown in the following sketch. If the heat transfer coefficients on the water side and on the air side are 550W/m2Kand55W/m2K respectively, calculate the overall heat transfer coefficient based on the outer diameter. The heat exchanger pipe is 5-cm, schedule 40 steel (k=54W/mK) with water inside.
Water flowing in a long, aluminum lube is to be heated by air flowing perpendicular to the exterior of the tube. The ID of the tube is 1.85 cm, and its OD is 2.3 cm. The mass flow rate of the water through the tube is 0.65kg/s, and the temperature of the water in the lube averages 30C. The free-stream velocity and ambient temperature of the air are 10m/sand120C, respectively. Estimate the overall heat transfer coefficient for the heat exchanger using appropriate correlations from previous chapters. State all your assumptions.
