5.11.2. A 150-m-long, 35-cm-diameter, concrete (smooth) pipeline raises water 40 m from a water supply reservoir to an elevated tank. A design flow rate is 120 L/s. Select the best pump (based on highest efficiency) from Figures 5.23 and 5.24 and determine its operating conditions (oo, Q, Hp, and e). Assume complete turbulence and minor loss coefficients that add up to 4.7. BARBARYS $929 22 Pup Heal Pump Head (m 70 60 20 10 Patie 1523 5 50 152 35 10² 15 2 3 5 Discharge d or 10 m 100 150 Q.
