You need to deliver 300L/s of water at 20C from a large, constant-level tank to another constant-level tank as shown in the figure. A centrifugal pump from the manufacturer-provided characteristic curves presented in the supplementary material with impeller and motor (pump speed) choice needs to be selected. All pipes in the system have internal diameter d=20cm and are made of plastic. The height levels in the figure are z0=5m and z2=10m. The section of pipe between points A (tank discharge) and B (pump inlet) has length LAB =10m and all accessories have an equivalent pipe length LAB,e=5m. The section of pipe between points C (pump outlet) and D (gate valve inlet) has length LCD=10m and all accessories have an equivalent pipe length LCD,e=5m. 1) For the current operation, determine the impeller size and pump speed that most closely match the desired delivery rate. 2) Can one of these pumps be used? If so, report it and indicate the expected efficiency. If not, propose a modification to the system in order to deliver water from tank 1 to 2
