Its capital is Wuhanthe composite name of the three former cities and now districts of HankouHanyangand Wuchangwhich lie at the confluence of the Han River and the Yangtze at a point approximately miles km from the sea and halfway between Shanghai and Chongqing.

Michell obtained patents for his turbine design inand the manufacturing company Weymouth made it for many years. Today, the company founded by Ossberger is the leading manufacturer of this type of turbine.

Unlike most water turbineswhich have axial or radial flows, in a cross-flow turbine the water passes through the turbine transversely, or across the turbine blades. As with a water wheelthe water is admitted at the turbine's edge.

After passing to the inside of the runner, it leaves on the opposite side, going outward. Passing through the runner twice provides additional efficiency.

When the water leaves the runner, it also helps clean it of small debris and pollution. The cross-flow turbine is a low-speed machine that is well suited for locations with a low head but high flow. A Bonneville Dam Kaplan turbine after 61 years of service The Kaplan turbine is a propeller-type water turbine which has adjustable blades.

It was developed in by Austrian professor Viktor Kaplanwho combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine.

Its invention allowed efficient power production in low- head applications which was not possible with Francis turbines. The head ranges from 10—70 metres and the output ranges from 5 to MW. Runner diameters are between 2 and 11 metres.

Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as The Kaplan turbine installation believed to generate the most power from its nominal head of Gorlov of Northeastern University.

The physical principles of the GHT work are the same as for its main prototype, the Darrieus turbine, and for the family of similar Vertical axis wind turbines which includes also Turby wind turbineaerotecture turbine, Quietrevolution wind turbineGHT, turby and quietrevolution solved pulsatory torque issues by using the helical twist of the blades.

This article lists hydroelectric power stations that generate power using the conventional dammed method. This list includes power stations that are larger than 1, MW in maximum net capacity, and are operational or under construction.

As ofthe largest hydroelectric power station is the Three Gorges Dam in Chinarated at 22, MW in total installed capacity. After passing on 7 December the 14, MW mark of the Itaipu Damthe facility was ranked as the largest power-generating facility ever built.

Power is generated by 32 turbines rated at MW, and two turbines rated 50 MW, which are used to power the facility itself. Construction of this dam commenced inand was completed innearly two decades after it started.

These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where net metering is offered.

There are many of these installations around the world, particularly in developing nations as they can provide an economical source of energy without the purchase of fuel.

Micro hydro systems complement solar PV power systems because in many areas, water flow, and thus available hydro power, is highest in the winter when solar energy is at a minimum. Micro hydro is frequently accomplished with a pelton wheel for high head, low flow water supply. The installation is often just a small dammed pool, at the top of a waterfall, with several hundred feet of pipe leading to a small generator housing.Start studying Geography - Three Gorges Dam, China.

Introduction to Asia. In this part of the Prezi we will focus on the geography and history of South and Southwest Asia: Again, the history surrounding the Asian continent is vast with many early civilizations & conquerors being a part of it Three Gorges Dam, Yubei province, China.

The Three Gorges Dam in China; the hydroelectric dam is the world's largest power station by installed capacity. Hydropower or water power (from Greek: ύδωρ, "water") is power derived from the energy of falling water or fast running water, which may be harnessed for useful purposes.

- Three Gorges Dam The Three Gorges are known to be a famous tourist attraction for its beautiful scenery, located in northeastern China along the Yangzi River.

The Yangzi River runs miles long, being the third longest river in the world after the Nile and Amazon Rivers. The Three Gorges are world famous as the most scenic section of the navigable reaches of the Yangtze, and the location of the Three Gorges Dam.

They form a series of natural and cultural attractions on a Yangtze Cruise between Chongqing and Yichang on the middle reaches of the Yangtze.
