.Buildings.Fluid.Movers.BaseClasses.Validation.EulerReducedSpeed .Buildings.Fluid.Movers.BaseClasses.Validation.EulerReducedSpeedSimilar to Buildings.Fluid.Movers.BaseClasses.Validation.EulerComparison, this model compares the power computed from the Euler number method with measured values. The power data at speeds N=4100, 3400, and 2500 RPM from the power map of Buildings.Fluid.Movers.Data.Fans.Greenheck.BIDW13 (shown below) was used. Note that the pressure curves in the figure do not seem to be independently measured but rather simply scaled from the nominal curve. However, because the Euler number method also does not account for the efficiency degradation along any curve Δp=kV̇2, using the Euler number method has equivalent accuracy to using such power maps.
