The Alaska Pipeline in the chapter-opener photo has a design flow rate of 4.4E7 gallons per day of crude oil at 60°C (see Fig. A.1).
(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.
Compare the time and cost of using the following three alternative methods for casting the concrete for the wall: 1) direct chute 2) pumped 3) crane and bucket.
