# .AixLib.Fluid.Movers.Compressors.Utilities.VolumetricEfficiency.PowerVolumetricEfficiency

Model describing flow volumetric efficiency on power approach

## Information

This model contains a calculation procedure for volumetric efficiency models (for more information, please check out AixLib.Fluid.Movers.Compressors.BaseClasses.PartialCompression). The calculation procedures based on a power approach are presented below.

#### Implemented approaches

Actually, one power approache is implemented in this package. To add further calculation procedures, just add its name in AixLib.Fluid.Movers.Compressors.Utilities.Types and expand the `if-structure`.
