2. Corsider a horizontal 120 cm-diameter galvanized-iron pipe simuating the Alaskan pipel ine. The oil flow is 300 million liters per day, at a density of 910 kg/m' and viscosity of C.01 kg/(m-s). Each pump along the line raises the oil pressure to 8 MPa, which then drops, due to head loss, to 400-kPa at the entrance to the next pump. Estimate (a) the appropriate distance between pumping stations and (e) the power required if the pumps are 88 percent efficient.

† 2. Consider a horizontal 120 cm-diameter galvanized-iron pipe simu'ating the Alaskan
pipeline. The oil flow is 300 million liters per day, at a density of 910 kg/m² and viscosity of
0.01 kg/(m-s). Each pump along the line raises the oil pressure to 8 MPa, which then drops,
due to head loss, to 400-kPa at the entrance to the next pump. Estimate (a) the
appropriate distance between pumping stations and (6) the power required if the pumps
are 88 percent efficient.
