A tube bank uses an aligned arrangement of 15-mm-diameter tubes with Sr = SL = 30 mm. There are 10 rows of tubes with 50tubes in each row. Consider an application for which cold water flows through the tubes, maintaining the outer surface temperature at40°C, while flue gases at 427°C and a velocity of 17 m/s are in cross flow over the tubes. The properties of the flue gas may beapproximated as those of atmospheric air at 427°C. What is the total rate of heat transfer per unit length of the tubes in the bank, inkW/m?q' =kW/mi
