This example is identical to
BuildingSystems.Fluid.Movers.Validation.PowerSimplified, except
that the efficiency of the flow controlled pumps
pump_dp and pump_m_flow is estimated by
using the Euler number and its correlation as implemented in
BuildingSystems.Fluid.Movers.BaseClasses.Euler.
The figure below shows the approximation error for the power calculation where the speed y differs from the nominal speed ynominal.
