A preheater involves the use of condensing steam at 100^{\circ} \mathrm{C}100 drgrees Celsius on the inside of a bank of tubes to heat air that enters at 1 atm and 25^{\circ} \mathrm{C}25 degrees Celsius. The air moves at 5 m/s in cross flow over the tubes. Each tube is 1 m long and has an outside diameter of 10 mm. The bank consists of 196 tubes in a square, aligned array for which S_{T}=S_{L}=15 \mathrm{mm}S
T=SL=15mm. What is the total rate of heat transfer to the air? What is the pressure drop associated with the airflow?
