Also can someone explain why there is a direct relationship between torque with current and speed with voltage in a generator?

Do you think any of these motors in the 120W or 150W range would be a good choice if run in reverse? How often do you have to change a brushed motor if the system is running constantly? http://www.maxonmotor.com/maxon/view/catalog

Do you have a link to examples of any models?

Why would a small number of blades be the most suitable design for this application? Like DEvens said above, I have looked at the impellers for some pumps that operate in this range and their geometry is a little more complex...

- It's for an academic research project so ideally I'll get some CFD analysis done. - Because of the nature of the enclosure the turbine must fit in, it must fit within a 3" diameter circular cross section. Any configuration is fine as long as it fits in this area. Thanks for your reply!

I'm working on a project right now which requires a hydro turbine generator system requiring 120W of power output capable of working with the following specs: Flow: 0.003m^s/s Pressure: 6m head By my calculations, this should require an efficiency of ~66%. All flow must be in the axial...
