The Alaska Pipeline in the chapter-opener photo has a design flow rate of 4.4E7 gallons per day of crude oil at 60 deg C A) assuming a galvanized-iron wall, estimate the total pressure drop required for the 800-mile trip. B) If there are nine equally spaced pumps, estimate the horsepower each pump must deliver.
Assume the pumps operate at an average efficiency of 65% and compare the amount of energy required to deliver 1 gallon of crude oil from Prudhoe Bay to Valdez to the energy content of the crude oil.
