3' head-1000 gpm plus
« on: October 16, 2010, 07:18:43 PM »
       hey all, I am considering a hydro turbine and need some help with the calculations. Here are my stats.
          head- 3'
          flow  1000 gpm plus
          penstock- none,  considering 10" SDR35 350' in length
          wire run- 2000'
      The turbine I would like to use is a banki with a high voltage alternator.
      What kind of power am I likely to be able to get to my batteries?
      Is 10" pipe large enough for the water I have ?
      Also,I'm not sure about the gpm, sorry. The stream flows around a large rock, through a space 6" deep by 24" wide,
      can gpm be calculated with this? The least amount of power to make this practical is 100 watts to the battery.
      Head could be increased by 2' by adding 500' of pipe
      Any information is a great help  Thank you

Wow that's a tough site. Unless you can get some really cheap 18 inch pipe there isn't any purpose to going the extra 500 feet. Any way to have an open canal or flume to move the 1000gpm part of the way?
  A 10 inch pipe would lose  1 3/4 feet head over 350 feet so you might get over 100 watts. A 12 inch pipe would lose .7 feet head. so 2.3 feet head and 1000 gpm could produce 230 watts.
You might consider something like the ESD low head hydro. It works on low head and high volume. Can you create a 3 foot high dam and have the overflow go into this type of turbine?
You can calculate the flow with a cross section to get square foot and multiply by speed of the water in foot per second. So 6 inch by 24 inch is 1 square foot.  If you throw a piece of wood into the stream and measure how far it travels in 10 seconds, multiply by 6 to get cubic feet per minute, and then multiply by 7.4 to get gpm.
How did you get the 1000 gpm number

2 thousand feet of wire? That's a LOT of money.

How will you protect/lay the wire. High voltage a/c could be buried http://www.sprinklerwarehouse.com/18-2-Multi-Strand-Irrigation-Wire-p/18-2.htm but I don't know about 2k feet of it.

      Hydro, I came up with 1000GPM like this. There are 2 streams comming together upstream from my site.
      The smaller stream runs through a culvert where it filled a 5 gallon bucket in under a second.
      I figured It for 500 GPM. The other stream is larger.

I really enjoyed this link/site.
Lots of great pics!
I didn't see this guys background, but it's plain to see he has some deep pockets!   and knows how to get things done.

It looks like he is an electronic engineer. Lots of electronics on his home page and a bunch of expensive hobbies. His country place looks like it took a LOT of money. I wouldn't like to be there during an eruption of that volcano though.

Very impressed!

That is a very well documented project!
Here is an interesting picture:



And this is after a transformer and cleaning up with a capacitor.  I wonder if this is the loaded or unloaded waveform?
He says:  "The switching of the TRIACs in the ELC, coupled with the inductance of the generator, causes some significant distortion to the waveform"

Yeah no kidding.  Check out the home-made transformer weighing in at 200 pounds! :o

His Xformer is a light weight, I am dreading the day I have to build mine! I am designing for 30Kva w/ a 6Kv input and a 242V out put going to need a small loader to move the thing :( I am avoiding the need for such high voltages like the plaque though. I love his workmanship on the transformer! Personaly I would have epoxy blocked them both or built them oil submerged.

After reading his and his friends Manuel and Ariela labors I'm not sure if this is a story of endless struggles with a final triumph or a wonderful hydroelectric instalation.       I'd love the results assunimg the leaks didn't short something out but Wow that was a lot of site prep and work.

Wow  :o  Good thing his soil didn't have too many rocks in it.  1000 gpm over 3' is interesting.  I'm not sure where I would start.  Maybe a very wide under shot wheel?

1000 gpm really is not all that much water in terms of cubic feet per second:

1000 gal/min / 7.48 gal/cf / 60 sec/min = 2.23 CFS

The wide undershot wheel would need lots of water coming into contact with each blade to move it at a decent rotational speed.  2 CFS would work fine for a rather narrow wheel, I would think
