Harris Hydroelectric Systems

A line of vertical axis DC Pelton generator Systems

• Operates efficently on 10 to 600 feet of head
• Operates efficently on 2 to 250 gallons/min. of flow
• Available with site selected alternator

HOW TO DETERMINE OUTPUT

1. Head or vertical drop from source to nozzle:

Head can be measured with a transit or level and a measuring stick of known length is sucessive steps, -or- a quick pipe can be assembled from numerous garden hoses and the pressure can be measured with the hoses full of water. This, too, can be done in sucessive steps.

0.43 P.S.I. = 1 foot of head:

2.3 feet = 1 P.S.I.

2. Flow in gallons per minute passing through nozzle:

A temporary dam can be built to measure flow. By timing the filling of a container of known volume the flow can be determined. Care should be taken not to dry up creeks, but leave enough water to maintain natural enviromental balances.

3. Diameter, length and condition of feeder pipe:

Generally, single nozzle systems with under 2000 feet of feeder pipe require a 2" pipe. A two nozzle systems needs a 3" pipe and four nozzle systems require a 4" pipe. This will keep pipe losses below 25%. Please inquire about specific pipe losses for your site.
