Air at 15.6°C and 1 atm abs flows across a bank of tubes containing four transverse rows in the direction of flow and 10 rows normal to the flow at a velocity of 7.62 m/s as the air approaches the bank of tubes The tube surfaces are maintained at 57.2°C The outside diameter of the tubes is 25.4 mm and the tubes are in-line to the flow The spacing S _n of the tubes normal to the flow is 38.1 mm and also S _p is 38.1 mm parallel to the flow For a 0.305 m length of the tube bank, calculate the heat transfer the heat-transfer rate. Draw a schematic of the problem statement.
