Greetings, I will admit that I am fairly new to this list but I have an interesting supply. I have the ability to get a water stream at about 2-3 GPM but at about 30PSI (sometimes higher if the rains have been good like they have this past month, which is bad for hiking, but whatever). I am a mechanical engineer and am planning on setting up a small, portable unit for charging up some 12v lead acid batteries off of it.
Most of the online documentation I have seen regards high flow rates but low head pressures. I am at the other end of the spectrum, I have a pretty decent pressure but very low flow. I am guessing that I will be able to use either a francis turbine or a impulse turbine of some sort. Then I am planning on at least starting with a DC motor and using that as a generator. I will work on the electronics in the near future but right now I have to figure out what type of turbine to use. The cheapest and maybe the most easily obtained turbine of this sort would actually be a centripetal pump used as a turbine. I have found a few websites discussing this setup, however they are all on a large flow rate. Since this low flow higher pressure is abnormal I haven't been able to find much to go off of. What would you guys (and gals) suggest I use as a turbine? I really don't know, Sort of going out and trying out all kinds of different centripetal pumps I am not sure where to start, or even look. Any turbine help or suggestion would greatly be appreciated! thanks a lot! Rick ------------------------ Yahoo! Groups Sponsor --------------------~--> Get fast access to your favorite Yahoo! Groups.
