A tube bank uses an aligned arrangement of \(30-\mathrm{mm}\) diameter tubes with \(S_{T}=S_{L}=60 \mathrm{~mm}\) and a tube length of \(1 \mathrm{~m}\). There are 10 tube rows in the flow direction \(\left(N_{L}=\right.\) \(10)\) and 7 tubes per row \(\left(N_{T}=7\right)\). Air with upstream conditions of \(T_{\infty}=27^{\circ} \mathrm{C}\) and \(V=15 \mathrm{~m} / \mathrm{s}\) is in cross flow over the tubes, while a tube wall temperature of \(100^{\circ} \mathrm{C}\) is maintained by steam condensation inside the tubes. Determine the temperature of air leaving the tube bank, the pressure drop across the bank, and the fan power requirement.
