20,000 lb/hr of air is to be cooled from 150°F to 100°F by water flowing in a shell-and-tube heat exchanger. Cooling water is available at 70°F and should leave the exchanger at 95°F. Available to do this cooling assignment is a one-shell pass, two-tube pass exchanged consisting of fifty 1-in OD 18 BWG copper tubes, each 10 ft long. The tubes are arranged inside a 10-in shell on a staggered 1-1/4- inch triangular pitch with baffles spaced every 6 in. Is this exchanger satisfactory?

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.

Hi I need asisstance with a thermo review problem, Thank you! A heat exchanger is used to heat air. The air enters at 300 K with a flow rate of 5 kg/s. The air is heated by a separate stream of H2O that enters the heat exchanger at 300 kPa, saturated vapor and leaves as saturated liquid. If the H2O flow rate is 0.2 kg/s, determine the exit temperature of the air (K). Cpair=1.027 kJ/kgK. Note the air and H2O areseparate streams. No mixing occurs.

K) at a rate of 10 kg/s with an inlet temperature of 90°C. The water used as coolant enters the heat exchanger at a rate of 8 kg/s with an inlet temperature of 10°C. The plant data gave the following equation for the overall heat transfer coefficient (in W/m2 K): 600 U = 1 (m. where m, and m, are the cold and hot stream flow rates in kg/s, respectively. (a) The existing unit is to be replaced. A vendor is offering a very attractive discount on two identical heat exchan gers that are presently sto cked in its warehouse, each with area of 5.5 m? Because the tube diameters in the existing and new units are the same, the above heat transfer coefficient equation is expected to be valid for the new units as well.
