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.

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
