Hi Duncan,
I'm unsure how much water you are using to get your 110 W amps. Running your numbers you would get about 240 watts using one of our Pelton turbines for every liter of water per second you use. A 20,000 liter tank would last about 5.5 hours and net you 1.3 kWhrs. What I'm aiming at is that if your existing set up isn't very efficient then changing the turbine to a more efficient unit might be a solution (this can cast as little as $500 US if you use one of our kits). Can you advise water flow rate at the 110 Watts stated ? What is the maximum output of the turbine you have been able to obtain. With a 100mm ID pipe flows of 1 l/s result in almost no head loss. This line is well capable of a few kW if you have the water.

How? Hi, Further info, Head about 50m. 150m of 4 inch pipe. Banki about 6 inch diameter Adjustable inlet up to about 3 inch width. Header tank 500 gallon. Power output 13.8V at 8A. guess 2500rpm. All figures estimates. In Winter runs continuously. In dry spells not enough water, so I wanted to automatically get intermittent full power, rather than no power. The generator self starts. regards, Duncan Irvine. --- In [EMAIL PROTECTED], "Nando" <[EMAIL PROTECTED]> wrote: > > The info supplied is too limited. > Detail, carefully, the Banki when working -- head of the water, volume, and > generator capacity. > RPM if you know, diameter of the Banki, the width of the Banki. > Volume size of the tank and the height of the tank in reference to the Banki > and if the Banki could be placed may feet or meters below the tank. > > Regards > > Nando > ----- Original Message ----- > From: "hwmdu" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Thursday, November 18, 2004 3:06 PM > Subject: [microhydro] Intermittant flow with a siphon.
