Problem 5: Crude oil flows through a level section of the Alaskan pipeline at a rate (in the old days!) of 1.6 million barrels per day (a U.S. petroleum barrel (bbl) is 42 U.S. gallons). The pipe inside diameter is 48 inches and its roughness is equivalent to galvanized iron. The maximum allowable pressure is 1200 psig and the minimum pressure to keep remnant-dissolved gas in solution in the crude oil is 50 psig. The crude oil has SG 0.93 ; its viscosity at the pumping temperature of 140°F is 3.5 x 104 Ibrs/ft2. For these conditions, determine the maximum possible distance between pumping stations. If the pump efficiency is 85 percent, determine the power that must be supplied at each of the pumping stations Problem 5: Crude oil flows through a level section of the Alaskan pipeline at a rate (in the old days!) of 1.6 million barrels per day (a U.S. petroleum barrel (bbl) is 42 U.S. gallons).
