For instance, for a system with a flow of 500 gallons per minute and a static head of 60 feet, the theoretical maximum power output is 5.65 kW. The system is prevented from 100% efficiency (from obtaining all 5.65 kW) due to the real world, such as: turbine efficiency, friction in pipe, and conversion from potential to kinetic energy.
A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes.

A schematic presentation of a gravitation water vortex power plant, showing the turbine in yellow. The gravitation water vortex power plant is a type of micro hydro vortex turbine system which converts energy in a moving fluid to rotational energy using a low hydraulic head of 0.7–3 metres (2 ft 4 in – 9 ft 10 in).

Small power plant of Licq-Athérey (Pyrénées-Atlantiques, France). An 1895 hydroelectric plant near Telluride, Colorado.. Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. [1]
The mostly used turbines are Pelton and Cross-flow types. Most of the MHP turbines are manufactured locally. The first turbine manufactured at the Balaju Yantra Shala Pvt. Ltd. (established 1960) was a 5 kW propeller turbine for the first MHP of Nepal in 1962. Kathmandu Metal Industries Pvt. Ltd., Nepal YantraShala Energy, Nepal Hydro & Electric Pvt. Ltd., Nepal Machine and Steel Structure, a
Low-head hydro power refers to the development of hydroelectric power where the head is typically less than 20 metres, although precise definitions vary. [1] Head is the vertical height measured between the hydro intake water level and the water level at the point of discharge.
Systems are less expensive when produced in quantity. Depends on power source - generally more economical given the larger scale of the generators. Photovoltaics, similar panels are used in all applications are affected less by this whilst wind power, where power scales approximately as the square of size is affected greatly.
