At the inlet to a constant-diameter section of the Alaskan pipeline, the pressure is \(8.5 \mathrm{MPa}\) and the elevation is \(45 \mathrm{~m}\); at the outlet the elevation is \(115 \mathrm{~m}\). The head loss in this section of pipeline is \(6.9 \mathrm{~kJ} / \mathrm{kg}\). Calculate the outlet pressure.
