Q3: You have been asked to choose a pump that can provide 105 ft head for 4000 gpm flow. The table below gives the pump curve data for a pump operating at 1000 rpm and has 3-in. impeller. The available pumps had different impeller diameter D and rotation speed N as shown below. Which pump can satisfy the required flow and head and which pump cannot? Use your own word to explain the reasons behind your decision? Standard Pump Flow (gpm) Head (ft) Pump 1 Pump 2 | Pump 3 N (rpm) D (in) 800 900 750 80 4 4 5 500 75 1000 73 1500 70 2000 67 2500 62 3000 58 3500 52
