Figure 5 is an illustration of the internal static pressure development. The difference between P1 and p1 is due to the impeller inlet absolute velocity head or dynamic pressure pV12/2, a much larger difference existing at the impeller exit, namely pV22/2. Losses in the collector result in the pump or stage outlet total pressure Pout being less than P2, the rise in total pressure APpmnp from port to port being Pout — Pin. In the figure, Pin is very nearly the same as P1, the inlet passage loss being comparatively small for most pumps.
