Entrance to centrifugal pump = pressure lost in entrance to container?

    Does the local pressure lost endured in an entrance to a container (k =1) equal to the same local pressure lost of an entrance to a hydraulic Centrifugal pump (in basic hydraulic with mostly ideal conditions - neglecting friction). Or do we ignore it as local pressure lost?

    Hi Femme_physics. Not sure exactly what you're asking but there is an irreversible loss in stagnation pressure anywhere there is flow unless work is being done on the fluid. So there's an irreversible pressure loss at the entrance to a pump and there's an irreversible pressure loss for flow into or out of a vessel. We typically analyze that pressure loss using the Darcy Weisbach equation or similar method.
