Oil with a specific gravity of 0.87 is being pumped
from a lower reservoir to an elevated tank, as shown. The
pump in the system is 78 percent efficient and
is rated 185 kW. Determine the flow rate
(L/s) of the oil in the pipe if the total head loss from
point 1 to point 2 is 12 m of
oil. Hint: P_{out }= Eff% *
P_{in}
