On this video you will know how to properly read a curve for a centrifugal pump, we see the Basic Concepts of the Graph, why we must make the selection at the point close to the point of greatest efficiency and how to select this point, we review some units of volumetric flow and its units, meters and feet of water as pressure units, we see why they are called flow pumps and pressure pumps.
the pump handles the pressure expressed in fluid column and the flow in mainly volumetric flow
