Dimensionless performance Tiny Cooling Fan fan curve

"Tiny Cooling Fan" non-dimensional performance parameters, but also the number of similar characteristics, so all similar fans, regardless of their size the size, height and density of the size of the speed of the fluid in the corresponding operating point K, they are dimensionless parameters equal. For a series of similar fans, each "Tiny Cooling Fan" has its own fan performance curve. When using the dimensionless coefficients indicate, this series all the corresponding conditions for a dimensionless point coincides operating point, the series all corresponding performance curve will coincide for a non-dimensional performance curve. Thus, for a similar series of fan performance "Tiny Cooling Fan", available in a set of non-dimensional performance curves.
