isn't there a formula like head in feet X gpm divided by 10 = approximate
wattage?

Hi Mac,
We worked for a while building controls for one company in Oz doing
small hydro, and I can share some observations, and things I learned
coming from a solar background:

> -100 kW range?
Yes, I believe this is
Again from little experience, but a diversion valve of the size of the
Penstock placed as far ahead of the turbine, (a long penstock reduces the
turbulence, turbulence reduces the turbines power.) Tnhis selector valve
can be AC or DC motorized, Belemo and other similar motors, they open
slowly,
Hi i have only worked on two so disregard if i am off track. Bob Gudgel of
Midnite solar helped me with ideas. It seemed to me the water keeps
flowing and if no load the turbine went fastest. As the load increased the
turbine slowed down, but generated more power until the turbine was
Mac,
I work with hydro power plants from 50W to 100kw. AC direct, DC, AC to DC,
stand alone and utility connected, in all sorts of configurations. Report back
with the turbine manufacturer and more specifics so that I may better advise
you. There are many routes one can take.
Clogging and
I don't really want to mess with changing the hydro, I'm more interested in
alleviating the manual transfer between power systems. I'm planning on
putting a power quality recorder/oscilloscope so that I understand what
type of power we are working with. Its semi-large (from my perspective)
isn't there a formula like head in feet X gpm divided by 10 = approximate

You need head (pressure) and GPM, clean degree free, no silt, a catch basin
to stall the water, big pipe long run, try to keep the rollercoasters out,
(rises), and no 90's, that's just to start. Low head waterwheels can
produce lots of power to but you need a river of water.

Hi Wrenches,
I've got a site visit for a largish ranch hydro site tomorrow. I am
relying on info from someone who doesn't know all of the nitty gritty
details about how the power system works (like size) but I want to try to
educate myself a bit. I know a bit about hydro but I'm no expert.
