I am looking at fan curves here at work and I stumbled upon this one. Its for an 80mm diameter tube axial fan.
What's up with the Flowrate vs RPM curve (the dashed line)?
In the flowrate interval between 12 - 23 CFM there are instances of the same RPM for different flowrates.
That doesn't make sense to me For a fixed geometry and a fixed RPM how on Earth can we have different flowrates?
Unless it is accounting for blade deformation?
Any thoughts?
