Fan or pump with ideally controlled speed Nrpm as input signal
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.
