Question: A pump is needed to pump 2 7 5 g p m of water through a 4 inch diameter pipe that is 1 7 0

A pump is needed to pump 275gpm of water through a 4 inch diameter pipe that is 1700ft long. The change in elevation is 105ft and the friction factor for the pipe is f=0.022. Au Aurora model 410 pump will be used and will be driven by an electric motor turning 3550rpm. Use the Aurora pump curve for a 22-1210 pump to answer the following:
a. What size pump should be used?
b. Using the pump from part a and with valve wide open what will be the actual flow through the pipeline.
c. Calculate the hydraulic power at Q=275gpm
d. Calculate the shaft power of the motor
e. What will be the maximum allowable NPSH (ft)?
