In Problem 5.13.1, what throughputs can be achieved when pumping gasoline alone? Use a specific gravity of 0.74 and viscosity of 0.65 for gasoline at the flowing temperature. Compare the pump head requirements when pumping diesel versus gasoline. Use the Hazen-Williams equation with a Cfactor of 145.
Problem 5.13.1
A pipeline 50 miles long, 16 in. outside diameter, 0.250 in. wall thickness is constructed of API 5LX-65 material. It is used to transport diesel and other refined products from the refinery at Carson to a storage tank at Compton. During phase I, a flow rate of 5000 bbl/hr of diesel fuel is to be transported with one pump station located at Carson. The required delivery pressure at Compton is 50 psi. Assume a generally rolling pipeline elevation profile without any critical peaks along the pipeline. The elevation at Carson is 100 ft, and the storage tank at Compton is located on top of a hill at an elevation of 350 ft.
(a) Using diesel with specific gravity of 0.85 and a viscosity of 5.5 cSt at a flowing temperature of 70°F, calculate the total pressure required at Carson to transport 5000 bbl/hr of diesel on a continuous basis. Use the Hazen-Williams equation with a C-factor of 125. The Carson pump suction pressure is 30 psi and the pump is driven by a constant-speed electric motor.
(b) Determine the BHP and motor HP required at Carson assuming 82% pump efficiency and 96% motor efficiency.
(c) What size electric motor would be required at Carson?
(d) Assuming a maximum allowable operating pressure of 1400 psi for the pipeline, how much additional throughput can be achieved in phase II if the pumps are modified at Carson?
