This pump must supply 0.4 m3 /s ofoctane to the main pump. All fittings are flanged; the pipe iswrought iron, schedule 80, 2 nominal, with L=65 m. The absolutepressure at section 2 is 282.5 kPa. Determine the power required tobe transferred to the liquid. Assuming the overall pump-motorefficiency is 65%, determine the input power required by themotor.  Sch 80, 2 Nom: ?? = 5.252 ????, ?? = 0.00015cm.  Octane: ?? = 701 ????/??3 , ?? = 0.51 × 10?3????/??2
