## Information

This package contains preconfigured versions of the mover models. They automatically configure a mover model based on `m_flow_nominal` and `dp_nominal`.

The configuration is as follows:

- The parameters `m_flow_nominal` and `dp_nominal` are used to construct the pressure curve Δ p = f(ṁ, y) where ṁ is the mass flow rate and y is the speed. This curve is based on a least squares polynomial fit of all pressure curves from BuildingSystems.Fluid.Movers.Data.Pumps for pumps and BuildingSystems.Fluid.Movers.Data.Fans for fans. (See also #1884.) The model identifies itself as a fan or pump based on the default density of the medium.
- The hydraulic efficiency is computed based on the Euler number. See BuildingSystems.Fluid.Movers.UsersGuide for details.
- The motor efficiency is computed based on a generic curve. See BuildingSystems.Fluid.Movers.BaseClasses.Characteristics.motorEfficiencyCurve for details.
