[TRNSYS-users] how to fix power consumption of a pump

[MEHMOOD Sajid]

Dear Trnsys Users,

I have a question regarding Pump Pump Consumption (Variable Speed Pump). I used forcing function to control mass flow rate of pump. And plotted result shows that  mass flow rate is different in different hours of the day. But power consumption of pump is constant. Common sense says that when pump flow rate is different, power consumption by pump should be different. is not it?
Please see attached figures (plotted results).

Please give your opinion in this regard.

Thank you.

Best Regards,
Sajid
