Crude oil flows through a level section of the alaskan pipeline at a rate of 1.6 million barrels per day (1 barrel = 42 gal). the pipe inside diameter is 48in.; its roughness is equivalent to galvanized iron. the maximum allowable pressure is 1200 psi; the minimum pressure required to keep dissolved gases in solution in the crude oil is 50 psi. the crude oil has a specific gravity of 0.93, and a viscosity of 3.5 x 10-4 lbf. s/ft2 at its pumping temperature.

Ibelieve the answer is d. titaniumhope my answer has you : )

Ithink the answer is d
