Question

A long, straight horizontal pipeline of diameter 350 mm and effective roughness size
0.03 mm is to be constructed to convey crude oil of density 860 kg/m3 and absolute
viscosity 0.0064 N s∕m2 from the oilfield to a port at a steady rate of 7000 m3/day.
Booster pumps, each providing a total head of 20 m with an overall efficiency of 60%,
are to be installed at regular intervals. Determine the required spacing of the pumps and
the power consumption of each.
