Question

5. [30 pts] The pipe shown below is old/rusty and very rough with the resistance coefficient fof 0.07. You propose to install two identical pumps (based on the pump curve from #4) in series to fill the reservoir on the right. What discharge will occur under these conditions? Include local (entrance and bend) and pipe head losses. Hint: Plot the system and pump curves.
