Net head refers to the difference in pressure across the turbine measured at the inlet and outlet.Net Head: Upstream Pressure - Downstream Pressure
Typical units for measuring head are:
PSI (Pounds per Square Inch) Feet (Elevation in feet from turbine inlet to surface of water) Meters (Elevation in meters from turbine inlet to surface of water) BAR (Metric unit of pressure)
Flow is a measure of the volume of water passing through the turbine per unit of time.
Typical units for measuring flow are:
GPM (Gallons per Minute) MGD (Millions of Gallons per Day) CFS (Cubic Feet per Second) LPS (Cubic Liters per Second) MPS (Cubic Meters per Second)
Electricity rates vary by location. The default value is loaded from the average U.S. national resale rate but for accurate estimation local rates should be used.
If you are unsure of your local power rates, state averages can be found on the U.S. Energy Information Administration’s (EIA) website. http://www.eia.gov/
Estimated continuous output is based on site head and flow conditions. Conditions typically vary throughout the day and year, contact Soar for a detailed analysis to more accurately estimate power output.
A conservative system efficiency of 75% is used to calculate the value shown.
Estimated revenue is based on an assumed 24/7-365 power generation. Contact Soar for a more detailed analysis that accounts for specific system performance.
Power generation potential depends on two primary metrics: head and flow. Head is the upstream water pressure while flow is a measure of how much water is passing through the pipe. By entering a local electricity rate, estimated annual revenue can also be calculated.
