What are the low-flow limits of microhydro?

Hi all.

Hope all's going regeneratively swell. Wondering if we can still generate electricity with a light flow of water, a mere mountain stream, not a river, not even a strong stream?   Much Thanks,  Ogre-Nick

There are two variable for micro-hydro power:
1) Height
2) Flow
Net Power = Flow (gpm) x Height (ft) x 0.1

So with a height of 100ft and a flow of 10gpm you could get
Net Power = 10gpm x 100ft x 0.1 =100W or (2400WH per day)

Actually height is usually a more limiting factor than flow.
