An in-line tube bank is constructed of 2.5-cm-diameter tubes with 15 rows high and 7 rows deep. The tubes are maintained at 90oC, and atmospheric air is blown across them at 20oC and u∞ =12 m/s. The arrangement has Sp = 3.75 and Sn = 5.0 cm. Calculate the heat transfer from the tube bank per meter of length. Also calculate the pressure drop.
