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.
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.
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 must be heated from 15 to 50°C in a simple double-pipe heat exchanger at a rate of 3,500 kg/h. The water is flowing inside the inner tube with steam condensing at 110°C on the outside. The tube wall is so thin that the wall resistance may be neglected. Assume that the steam-film coefficient h_0 is 11 kW/m^2 °C. What is the length of the shortest heat exchanger that will heat the water to the desired temperature, considering an optimal diameter for the tube? Checking several table values, the following properties of water for this scenario are: p = 993 kg/m^3 k = 0.61 W/m °C \mu (viscosity) = 0.78 cP Cp = 4.19 J/g °C
Hot water flowing at 0.015 m3/min enters the tube side of a counter current shell & tube heat exchanger at 80 C and leaves at 50 C. Cold oil flowing thru the shell at 0.05 m3/min, with density 800 kg/m3 and specific heat of 2.0 kJ/kg K, enters at 20 C. Consider water specific heat at 4.2 kJ/kg K and density of 988 kg/m3 at above condition, what is the approximate Log Mean Temperature Difference (LMTD)? Show the temperature profile completely labeled.
