A preheater involves the use of condensing steam at 100°C on the inside of a bank of tubes to heat air that enters at 1 atmosphere and 15°C. The air moves at 8 m/s in cross flow over the tubes. Each tube is 2 m long and has an outside diameter of 5 mm. The bank consists of 196 tubes in a square, aligned array in which the distance between tube centers is 15 mm. What is the temperature of the air after passing through the tubes. Also, what is the pressure drop associated with the air flow?

Calculate the convective heat transfer rate via the top and the two side walls of a refrigerated box trailer as shown in the figure. The trailer is cruising at a rate of 70 mph (31.3 m/s). The box trailer dimensions are 16 m long, 4.1 m high, and 2.6 m wide. Assume that the surface of the trailer is at uniform temperature of 10°C. The air temperature is 30°C. Because of the presence of the prime-mover in the front, the air flow can be assumed to be turbulent when it encounters the trailer. 187.4 kW Walls. Prime-mover 16 m 2.6 m

Air is to be heated by passing it across the tubes of an in-line tube bundle consisting of 8 rows of 25 mm OD tubes in the direction of flow and 10 tubes in each row normal to the flow. Air approaches the tube bank in the normal direction at 30 °C and 1 atm with a mean velocity of 10 m/s. The tube spacing is 37.5 mm in both parallel and normal to the flow. Calculate the heat transfer from the bundle per m of length when the tube surface temperature is 90 °C.
