A shell and tube heat exchanger with one-shell pass and multiples of two-tube passes is constructed from \(0.0254 \mathrm{~m}\) OD tube to cool \(693 \mathrm{~kg} / \mathrm{s}\) of a \(95 \%\) ethyl alcohol \(\left(C_{p}=3810 \mathrm{~J} / \mathrm{kg}-\mathrm{K}ight)\) from \(66{ }^{\circ} \mathrm{C}\) to \(42{ }^{\circ} \mathrm{C}\), using \(6.3 \mathrm{~kg} / \mathrm{s}\) of water available at \(10^{\circ} \mathrm{C}\left(C_{p}=4187 \mathrm{~J} / \mathrm{kg}-\mathrm{K}ight)\). In the heat exchanger, 72 tubes will be used. Assume that the overall heat transfer coefficient based on the outer-tube area is \(568 \mathrm{~W} / \mathrm{m}^{2}-\mathrm{K}\). Calculate the surface area and the length of the heat exchanger.
