I want to be geeky!!!
We're so near, closing the gap between the theoretical, and the practical...
The thing is, it would be just as easy to measure the torque of a pump impeller, as it would to measure a fan's... I have this mental picture of a belt driven pump: it would be easier to measure that, I think!
I also have another picture: a pump mod where the impeller is replaced with one that is a bit thicker, to minimize the loss of energy at that point.
