    Sizing a centrifugal pump in an oil storage tank battery

    It just does not make sense. The tank is 20' tall, and I want to pump the tank down to 4', but need 150 psi discharge. The pump curve shows I need 9' NPSH required. So if I get to add, static pressure, let's just say (2.31 x 16'= 36')to the 9' That would mean I should be able to pull a vacuum...
