Air at 1 atm and 10°C flows across a bank of tubes 15 rows high and 5 rows deep at a velocity of 17 m/s entering the in-line array. The tubes have a 1.25 inch outer diameter and all tube surfaces of the tubes are all maintained at 220°C. The tube bank is arranged in-line such that the spacing in both the flow normal and parallel directions are each 1.875 inches. Find the total heat transferred per unit length for...

Tube bank uses an aligned arrangement of 10-mmdiameter tubes with ST-Si-20 mm. There are 10 rows of tubes with 50 tubes in each row. Consider an application for which cold water flows through the tubes, maintaining the outer surface temperature at 27°C, while flue gases at 427°C and a velocity of 5 m/s are in cross flow over the tubes. The properties of the flue gas may be approximated as those of atmospheric air at 427°C. Using Zukauskas correlation determine...
