The Alaskan pipeline is 48 in. ID, 800 mi long, and carries crude oil at a rate of 1.2 million bbl/day (1 bbl = 42 gal). Assuming the crude oil to be a Newtonian fluid with a viscosity of 25 cP and SG of 0.87, what is the total pumping horse power required to operate the pipeline? The oil enters and leaves the pipeline at sea level, and the line contains the equivalent of 150 908 elbows and 100 open gate valves. Assume that inlet and discharge pressures are 1 atm.
