I know very little about this subject and would appreciate it if you send me information or lead me to the right website such as this. Thanks, Damian Hi,

Gibson Thu, 26 Nov 2009 21:45:56 +0000 http://smallhydro.com/?p=1048#comment-162 Hey guys, I was speaking with a relative and they mentioned hearing about a form of micro hydro that I want to learn more about. I don't know the specific term or reference, but essentially, it is a 40' x 8"(diameter) tube that you place in a river. My understanding is that it is a self contained DC unit and several can be placed in the river with no harm to wildlife. Anyone know about this, what it is called, their efficiencies, or who makes them? Cheers, G. Gibson Hey guys,

One thing you should look into is the Penstock design software regarding PipeFlow - Check back through our site linke for great price breaks that they offer our readers from time to time. Using that dynamic flow analysis software you can get a great estimation for Hydropower Pipeline or Penstock Head loss. You should check it for max and min flow regimes. Yes your FDC curve should be analyzed typically using the 50% point or the 80-20% rule - that will account for the Mid more typical flows. This number will strongly depend on your FDC shape. A broad high FDC may be worth having a larger penstock and turbine because the higher value in the large flows. A sharply dropping max end of the curve is a warning to not plan for large ROI from flows on that end of the FDC. Azeem,
