Octane is to be pumped in a piping system that is routed from storage tanks to the main pump by a number of smaller pumps. One such arrangement is shown below. This pump must supply 0.4 m3 /s of octane to the main pump. All fittings are flanged; the pipe is wrought iron, schedule 80, 2 nominal, with L=65 m. The absolute pressure at section 2 is 282.5 kPa. Determine the power required to be transferred to the liquid. Assuming the overall pump-motor efficiency is 65%, determine the input power required by the motor. Sch 80, 2 Nom: ?? = 5.252 ????, ?? = 0.00015 cm. Octane: ?? = 701 ????/??3 , ?? = 0.51 × 10?3 ????/??2
