OK, here goes.... since my shit burned to the ground I have some spare time. I want to make some green energy. Now, before you quit reading... look...
I have a lake that will be 15 acres. I want to build a waterwheel. Not one of those pansy paddle wheel water wheels, a real old style water wheel.
I couud use a Pelton wheel, but my drop is only about 20'. I am afraid it is not enough drop to power a pelton (yes, I have one from the late 1800's, or early 1900's) They use less water. Also, much less torque.
So, if a water wheel could grind flour, or run a saw mill, why not run my generator?
So, here is what we have:
15 acre lake... it has hundreds of acres of run off into it. I have an 8" drain pipe. I opened the pipe for a week, had 1.5" of rain, lake was at the same level with draining constant + rain.
I'd like to run a 5k generator (but 3K would probably be more than enough for most of the time)
I understand I will not be able to run the gen all the time.... but:
15 acres x 43500 (sq. ft per acre)(rounding here)=652600 sq. ft.
If I only allow 1' water drop that equals 652600 sq. ft x 1' depth = 652600 cubic ft. of water.
now, cu ft x 7.48052= gallons.... so that equals 4,881,039 gallons. Let's round it to 4,800,000 gallons.... easier.
Now, here comes my questions.... what size drain pipe do I need with what size water wheel to run the generator.
I am struggling to find flow per min of an 8" pipe.
