1. Crude oil flows through an uphill section of the Keystone pipeline at a rate of 2.94 m3 /s (equivalent to 1.6 million barrels of day). The average elevation gain in the section of pipeline is 10 m per kilometer. The pipe diameter is 1.2m. The maximum allowable pressure in the pipe (at the inlet) is 8.27 MPa; the minimum pressure (at the exit) required is 3.45kPa. The crude oil has density 930kg/m3 and a dynamic viscosity of 1.68×10-2 Pa.s. For above condition consider the surface roughness factor is 0.26 mm. Determine the maximum possible distance between pumping station with and without elevation gain. Use Haaland equation for friction factor.
