.BuildingSystems.Fluid.Movers.BaseClasses.Euler.efficiency

Information

This function uses the correlation of Euler number to compute the efficiency η.

Interface

function efficiency
  extends Modelica.Icons.Function;
  input BuildingSystems.Fluid.Movers.BaseClasses.Euler.peak peak "Operation point with maximum efficiency";
  input Modelica.Units.SI.PressureDifference dp "Pressure rise";
  input Modelica.Units.SI.VolumeFlowRate V_flow "Volumetric flow rate";
  input Real V_flow_dp_small(final unit = "m3.Pa/s", min = Modelica.Constants.eps) "Small number for regularisation";
  output Modelica.Units.SI.Efficiency eta "Efficiency";
end efficiency;
