There are two options for specifying the momentum flux:

specifying a mass flow rate postprocessor, which is then divided by the area of the inlet, which may also be a postprocessor.
specifying an inlet superficial velocity postprocessor and a density functor. The functor is usually a functor material property, defined by a GeneralFunctorFluidProps.

The scaling factor may be used if the inlet is not aligned with the X or Y direction, in which case a projection is necessary and this boundary condition should be used for both components of the momentum equation.

This boundary condition works with postprocessors, which may be replaced by constant values in the input. The intended use case for this boundary condition is to be receiving its value from a coupled application, using a Receiver postprocessor.
