Abstract (en)
[origin: WO2021032255A1] The invention relates to a method for quantitatively determining an actual operating-state-dependent variable, for example the pressure increase of a fan, wherein, an actual operating-state-dependent variable is determined via its rotational speed using known volume or mass flows of the fan.
