- You must select a submerged centrifuge multicellular pump for a borehole on a worksite that requires a flow of 1.500l/s. The borehole itself is 150m deep (see figure 5). If the outlet pipe has the following properties, then: wwww wwwwwww Water outlet (open air) wwww Outlet pipe L = 200m Borehole wwwww Pump f= 0.04 D = 38mm Figure 5 Borehole and pumping schematic A) Choose a pump from those presented in figure 6 (you must select the most adequate model) if there is no local head-loss, only friction related head-loss. You must draw the complete characteristic curve for the pipe directly on figure 6.; B) Is cavitation an issue if NPSHrequired is 5m briefly discuss the results.
