Question

Crude oil flows through a level section of the Alaskan pipeline
at a rate of 250 thousand cubic meters per day. The pipe inside
diameter is 1000 mm; its roughness is equivalent to that of
galvanized iron. The maximum allowable pressure is 8.3 MPa; the
minimum pressure required to keep dissolved gases in solution in
the crude oil is 340 kPa. The crude oil has SG = 0.93; its
viscosity at the pumping temperature of 60 ^{o}C
is μ= 0.017 kg/(m s). For these conditions,

Determine the maximum possible spacing between pumping stations.

Enter the spacing in kilometres, rounded to the nearest integer.

A pipeline transporting crude oil (sg = 0.93) at 1200 L/min is
made of 6in schedule 80 steel pipe. Pumping stations are spaced 4
km apart. If the oil is at 10 degrees Celsius, determine the
pressure drop between stations and the power required to maintain
the same pressure at inlet of each pipe. If the oil is heated to
raise the temperature from 10 degrees to 100 degrees Celcius at a
step of 1 degree, in each case, determine:...
