This model describes a fan or pump with prescribed speed in revolutions per minute.
The head is computed based on the performance curve that take as an argument
the actual volume flow rate divided by the maximum flow rate and the relative
speed of the fan.
The efficiency of the device is computed based
on the efficiency curves that take as an argument
the actual volume flow rate divided by the maximum possible volume flow rate, or
based on the motor performance curves.
See the
User's Guide for more information.
