No idea of the size. Propeller turbines are not common for micro hydro as the very small ones tend to block up.

If that thing is as big as it looks then you will need a very large flow of water. As long as you can supply that then it should work fine.

It will not be a Kaplan ( variable pitch blades) so you will need to work round its speed and load characteristics.

You need to be up in the 100 gallons/minute region for a small reaction turbine.

Flux, the impeller is five inches in diameter. The unit will be first tested in a creek that passes through my land. The volume of the spring run off is huge and every year I have wanted to test this idea.Yes the true kaplan does have variable pitch blades. This will probably limit me to small output.

as the very small ones tend to block up

I will use a culvert attached to the output this will create the vaccume needed to keep the runner free. Every year I see the water flowing from that 5 foot opening for almost a month. Lots of power there.
