9. A 300 m long 0.2 m diameter steel pipe connects two
reservoirs. The upstream reservoir is located 200 m higher than the
downstream one. How much energy is needed to be delivered by a pump
in order to supply 0.05 m3 /s discharge? Determine the power
required to deliver the flow if the efficiency of the pump is 80
percent. If the electric motor driving the pump is operated at 3600
rpm, determine the torque acting on the drive shaft. Ans: 203.5 m;
167 hp; 330 Nm
