A 280-km-long pipeline connects two pumping stations. If 0.56 m³/s are to be pumped through a 0.62-m-diameter line, the discharge station is 250 m lower in elevation than the upstream station, and the discharge pressure is to be maintained at 300,000 Pa, determine the power required to pump the oil. The oil has a kinematic viscosity of 4.5 × 10^-6 m²/s and a density of 810 kg/m³. The pipe is constructed of commercial steel. The inlet pressure may be taken as atmospheric.
