Whether you're designing a mini hydro turbine or the next Three Gorges Dam, this hydroelectric power calculator will help you estimate the power output of your project. Our tool finds the expected power for **three different types of hydroelectric turbines** from just the basic flow characteristics: the channel cross-section, flow velocity, and (for a dam) the so-called **head** — the usable fall height. Our hydroelectric power calculator is able to find the output of three different types of turbines: a **dam**, a **"run-of-river" installation**, and a **tidal power turbine**. The **power output of a dam** is calculated using the potential energy of the water and can be found using the following hydropower formula:. The **efficiency** of the turbine is the ratio of available energy of water to the actual power output of the turbine. Once you know the dam's power output, you can use our hydroelectric power calculator to determine the revenue it will bring you.

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:. The default value is loaded from the average U.S. national resale rate but for accurate estimation local rates should be used. 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. Head is the upstream water pressure while flow is a measure of how much water is passing through the pipe.

> **NOTICE: Many people ask if it is feasible to generate electricity with one of these hydroelectric turbines by installing it in a water system powered by an electric motor-driven pump. They charge batteries 24 hours a day and the power can be drawn from the battery as needed, As little as 100 gallons per minute (GPM) falling 10 feet through a pipe, or 5 gallons per minute falling 200 feet through a pipe, can supply enough power to operate lighting and small appliances a small cabin or household. > By contrast, larger typical AC power hydroelectric systems, designed to deliver ready-to-use 120/240 VAC power, are not practical for most people because they need a constant water supply large enough to supply the peak power output that will be required, usually a minimum of several thousand watts, requiring hundreds or even thousands of gallons per minute, depending upon the pressure available. If you believe you have a site suitable for a larger AC hydroelectric system like this, use the output calculator immediately below and then go to our Large Hydroelectric Generator page.

## Estimating WaterHead and WaterFlow of Micro Hydro Power Station/Plant. A full feasibility study will needed to generate accurate waterhead and water flow rates, but it can be helpful to get a very rough and ready estimate of this before making your enquiry. The waterhead is the height difference between where the water would enter the hydro power system and it would leave it, measured in metres. With hydro it is very important to get as much water head as you possibly can, as more water head means more power for not much more cost. Depending on how much water flow you have, the minimum amount of head required for a viable hydro system varies. You need to estimate the average annual flow, and not the flow on the wettest day of the year.Read More on How to Measure Water Flow?
