Be aware that US gallons are smaller than ours. It is usually simpler to use litres per second in your calculations. 10 gal/min is not a lot of water however you look at it (about 0.7 litres per second) but useful for battery charging. > The >usable head is about 130feet. I was considering a 2 inch pipe to a 4- >nozzle harris pelton (often used with less nozzles). Pipe run >600feet. Electricity run 50feet. Your 2" bore pipe (63 mm overall) will carry 20-25 USgpminute but this does not sound as if it happens much. You could save money with very little loss by going to 1.5" bore pipe. > I only wish to get some free energy, >I still expect to use the diesel generator a lot, but 250watts for >half the year would be nice. You will need about 20-25 gpm (1.3-1.6 litres per second) to get 250 watts. It seems you might usually only get 50-100 watts. This is still very useful over 24 hours, giving 1-2 kilowatt hours of energy. >I have no experience with hydro >whatsoever. Hope this makes things clearer. ray I may be able to help you. I can supply the turbine and controller if you want and help you out with design details.
