8. Crude oil flow through a level section of the Alaskan pipeline at a rate of 2.94 m³s'. The pipe inside diameter is 1.22 m; its roughness is equivalent to galvanized iron. The maximum allowable pressure is 8.77 MPa; the minimum pressure required to keep dissolved gases in the oil is 344.5 kPa. The crude oil has SG=0.93; its viscosity at the pumping temperature of 60°C is 0.0168 Pa. s. For these conditions, determine the maximum possible spacing between pumping stations. If the pumping efficiency is 85%, determine the power that must be supplied at each pumping station.

Transcribed Image Text:8. Crude oil flow through a level section of the Alaskan pipeline at a rate of 2.94 m³ s'. The pipe
inside diameter is 1.22 m; its roughness is equivalent to galvanized iron. The maximum allowable
pressure is 8.77 MPa; the minimum pressure required to keep dissolved gases in the oil is 344.5
kPa. The crude oil has SG=0.93; its viscosity at the pumping temperature of 60°C is 0.0168 Pa. s.
For these conditions, determine the maximum possible spacing between pumping stations. If the
pumping efficiency is 85%, determine the power that must be supplied at each pumping station.
