Angular velocity of the Fixed displacement pump

How can i give the angular velocity of the fixed displacement pump, should i use a constant value and add it to the ideal agular velocity source than connect it to the fixed displacement pump or instead of this simply give the value of the nominal shaft angular velocity through the block diagram of the pump.

Hi Yaseer,

You should use the constant value with the Ideal angular velocity source, as shown in the picture. As described in the documentation page below, the value of the Nominal shaft angular velocity parameter affects the pump efficiency characterization:
