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. C) Determine the supplied power output by the pump (in kW) as well as the absorbed power output when the pump reaches it's operational flow for the pump you have selected. | N.B. Hypothesize that water in the borehole is level with the pump intake. The pump intake is the same diameter as the outlet pipe. Patm-100…
