Consider a horizontal 4-ft diameter galvanized iron pipe simulating the Alaskan pipeline. The oil flow is 70 million U.S. gallons per day, at a density of 910 kg/m³ and viscosity of 0.01 kg/m:s. Each pump along the line raises the oil pressure to 8 MPa, which then drops to 400 kPa at the entrance to the next pump due to head loss. Estimate the appropriate distance between pumping stations and the power required if the pumps are 88 % efficient.

Question
Consider a horizontal 4-ft diameter galvanized iron pipe simulating the Alaskan pipeline. The oil flow is 70 million U.S. gallons per day, at a density of 910 kg/m³ and viscosity of 0.01 kg/m-s. Each pump along the line raises the oil pressure to 8 MPa, which then drops to 400 kPa at the entrance to the next pump due to head loss. Estimate the appropriate distance between pumping stations and the power required if the pumps are 88 % efficient.
