•
Steady State Power Consumption:
Depends on the actual speed, pressure, and flow.
visualizes the steady state power consumption for different operating points.
•
Peak Power Consumption (short time):
Occurs during acceleration and depends on the rotational
speed and the acceleration rate.
visualizes the peak power consumption.
