Gasoline flows in a long, underground pipeline at a constant temperature of \(15^{\circ} \mathrm{C}\). Two pumping stations at the same elevation are located \(13 \mathrm{~km}\) apart. The pressure drop between the stations is 1.4 \(\mathrm{MPa}\). The pipeline is made from 0.6-m-diameter pipe. Although the pipe is made from commercial steel, age and corrosion have raised the pipe roughness to approximately that for galvanized iron. Compute the volume flow rate.
