A centrifugal pump having a 6-in.-diameter impeller and the characteristics shown in Fig. 12.7 is to be used to pump gasoline through \(4000 \mathrm{ft}\) of commercial steel 3-in.-diameter pipe. The pipe connects two reservoirs having open surfaces at the same elevation. Determine the flowrate. Do you think this pump is a good choice? Explain.
