How to understand the Tiny Cooling Fan centrifugal fan performance curve

Qualitative analysis and discussion of the theoretical curves measured performance "Tiny Cooling Fan" centrifugal fan performance curve, namely the pressure p, efficiency?, Power and flow rate Q N curve, with centrifugal pump performance curve is completely analogous. However, due to differences in the physical properties of the fluid, such that "dota雷竞技 " In practical applications, the centrifugal fan and the pump performance curve is different. Centrifugal fan static pressure, static pressure efficiency curve, "dota雷竞技 " centrifugal fan performance curve dimensionless all have important applications in the fan.
