Hydro?

So I know that this is not really general solar but it is general so I thought this was the best place. I am hoping that someone would be able to help me find info on micro hydro. I am looking to use a well that flows 24/7. Not sure on the rate but it pushes through a 3/4 pipe at ground level. If need be I could hook up there or I could run it out a ways and I would be able to get about ten feet of head.

Re: Hydro?

From another thread where a person asked about pumped storage hydro with a 5,000 gallon tank: You can use a site like this:

http://www.oregon.gov/ENERGY/RENEW/H...ro_index.shtml

To figure out how much power you can generate for 5,000 gallons of water with a ~47 foot head flowing at ~7.48 gallons per second:
Gross Head x Flow x System Efficiency (in decimal equivalent) x C = Power (kW)
C is a constant (the value is different in English and metric units).
• 100 psi / 2.13 psi per foot * 1 cf/s * 0.55 turbine eff * 0.085 = 2.19 kWatts
• 5,000 gallons * 1/7.48 gallons per cuft * 1/1cf per sec = 668 seconds = 11 minutes of power
Looks like a lot of "work" for little "work"... 2kWatts for 11 minutes.

Re: Hydro?

A while back someone here posted this link. It's not exactly micro, but it's really worth a read for anyone interested in home brew hydro:
