A single-pass shell and tube heat exchanger (condenser) heats \(946 \mathrm{~m}^{3} / \mathrm{h}\) of water from \(10{ }^{\circ} \mathrm{C}\) to \(38{ }^{\circ} \mathrm{C}\). The heat exchanger uses a plain steel tube \(\left(\mathrm{k}: 45 \mathrm{~W} / \mathrm{m}-{ }^{\circ} \mathrm{C}ight)\) with an internal diameter \(0.0266 \mathrm{~m}\) and an outside diameter \(0.0333 \mathrm{~m}\). Steam is supplied at \(107{ }^{\circ} \mathrm{C}\) with the steam-side heat transfer coefficient equal to 68143 \(\mathrm{W} / \mathrm{m}^{2}{ }^{\circ} \mathrm{C}\). The water-side heat transfer coefficient is equal to \(1937 \mathrm{~W} / \mathrm{m}\). The mass velocity through the tube is equal to \(8258.3 \mathrm{~kg} / \mathrm{m}^{2}-\mathrm{s}\). Calculate the number of tubes required and the length of the tube.
