Fluid Mechanics: Bernoulli Equation Pump Problem

Water at 20 degrees Celsius is pumped at a constant rate of 9m3/h from a
large reservoir resting on the floor to the open top of an experimental
absorption tower. The point of discharge is 5 m above the floor, and
friction losses in the 50-mm pipe from the reservoir to the tower amount
to 2.5 J/kg. At what height in the reservoir must the water level be
kept if the pump can deliver only 0.1 kW?

I’m thinking we need to use the Bernoulli equation that accounts for
pump work, right?



=2 for laminar flow.
