Hi,
I'm trying to make sense of the attached pump datasheet and see how the information there relates to input fields for the Pump:ConstantSpeed object.
The Pump:ConstantSpeed object needs:
- rated power consumption (W)
- rated flow rate (m3/s)
- rated head (Pa)
- motor efficiency
Here's information available in the datasheet that seems relevant (there's more in there):
- motor rated power P2: 7.5 kW
- flow rate: 946.9 L/min (0.0158 m3/s)
- head: 20 mAq (196200 Pa)
- pump+motor efficiency at full load: 68.4%
- pump efficiency at full load: 74.4%
-
motor efficiency at full load: 90.4% (which is also 68.4% / 74.4%)
Now, here are my observations and questions.
