Hydro Power

huge power generators are placed inside dams. Water flowing through the dams spin turbine blades (made out of metal instead of leaves) which are connected to generators. Power is produced and is sent to homes and businesses.

a river or a reservoir leading into a river

There are several. Gravitational potential energy is transformed into linear kinetic energy, which is then transformed into rotational kinetic energy, which is then transformed into electrical energy.

That would depend on the dam - specifically, the amount of water that flows through, and the difference in height that can be obtained.

Potential energy is calculated as: PE = mgh; in SI units: potential energy (in Joule) is equal to the mass (in kg) times the gravitation (9.8 m/sec square) times the height (in meters); you can use this to calculate energy.

If you are interested in power, assume that a certain amount of water flows through every second - the result will be Joule / second, that is, Watts.

The Hoover Dam is only one dam. If you are talking about all the dams on the Colorado River there are six dams Glen Canyon dam, Hoover dam, Davis dam, Parker dam, Paulo Verde Diversion dam, and Imperial dam.

how tall is the model

The advantages of tehri dam is to provide electricity & hydel energy [generating electricity when water falls from a height].

The disadvantages are visible that lakhs of people houses were submerged in the making of dams there lands all the things .,the property submerged in the water. They are roaming here & there the government only decide to give money but never do this. you asked a question but now i am asking all the Indians , government ,this question are all the people are happy as they were in there old lands..................................................................

dams were actually built in Ancient Mesoptamia. i dont know the time though.

Hydrothermal means, quite literaly. The process is used to produce 'green' electricity. The heat from the centre of the Earth is used to turn water into steam. The steam is then used to turn the turbine, which then turns the generator and so produces electricity.

The disadvantages are that the change in water flow will effect the fish and making space to put the hydro facility can cause the deaths of plants and animals aswell as destruction of habitat. Hydroelectiric facilities do not produce much electricity compared to other renewable sources.

Electricity is used in an extraordinarily broad variety of ways. It finds application in domestic and commercial settings, as well a strong use in the industrial facilities that support our lifestyles. We use electricity as meanings of gaining on-the-spot access to (electrical) energy that can be changed into mechanical energy by motors. We use electric motors in thousands and thousands of items from tools and machinery to appliances to entertainment equipment. We light the heck out of our world using electric power. It's a huge application.

Electricity is something many of us take for granted. It is "behnid the scenes" in propping up the infrastructure of modern society. We light areas we use. Heat and cool places where we work and live. We ship, store, vend and prepare food with electricity. We work and relax using technology that is electrically powered.

Imagine a world without electricity. Get a small notepad and log each event every day that involves something you did that required electricity. It could be either direct application like lighting a room or working on a computer, or indirect, like using something that was manufactured using electricity. Our lives are powered up either directly or indirectly by electricity. Grabbing a backpack and hiking off into the woods is about the only way to get away from it. Oh, and leave behind all the things that were manufactured using electricity. Like you pack. And your equipment and packaged food and water. And your clothing.

Wherever there is water and a hydroelectricity plant. It can be found in most coastal regions and at most resorivers and rivers/ lakes.

They are both used as heating for homes, air, and water. They are also used for transportation for many uses. If you would like to learn more go to Wikipedia and search "Coal". Please support Wikipedia so it won't be gone and so we will be able to use this powerful internet source.

we use the most hydroelectric power in kansas

Use a solar Pannel

To have a brighter future

Use the sunshine

To lighten up your world

• They are both renewable sources of energy, that is, they can be used over and over and the power keeps coming.
• Neither emits any greenhouse gases or any other pollution, as fossil fuels do, so they contribute nothing to global warming.
• They are both expensive to establish at the moment but are slowly becoming cheaper (or solar panels certainly are), but they are the future of energy generation.

Theere are a great many waterfalls in New Zealand, as the terrain is generally not flat and most areas get reasonable to high rainfall. Therefore there are many streams and rivers that run over several abrupt changes in level, creating waterfalls.

The allies standard was the Colt 45 while the Germans had Lugers.

A more detailed answer is US: M1911 .45 ACP, Smith and Wesson Model 10 (Victory Model).38

UK and Commonwealth: Webley Mk IV .38, Browning Mk 2 .38 and Browning(Ingliss) Hi-Power 9mm

Japan: Nambu 9mm

Germany: Walther P38, Luger 9mm.

USSR: Moisin Nagant M 1895 Revolver 7.62, Tokarev TT Automatic 7.62

There are several other handguns used but the above were the most widely distributed.

Note: Over 500,000 Victory models were distributed to the US and UK forces during WWII.

Very carefully

More seriously, there are two main types of hydrolectric installations: Impoundment, and run-of-river (there's also electricity generation from the tides, waves, etc, but we'll leave those aside for now).

The impoundment types are probably what you're thinking of when you say 'hydro dam'. These are large dams which create a reservoir upstream. The water in the reservoir is then forced to flow through penstocks within the dam which direct the flow to where it can power turbines which are in turn used to generate electrcity. The dams themselves are usually concrete, while the turbines are usually metal.

The run-of-river type involves diverting water from a river and once again using it to turn turbines. The turbines are again usually metal. They can be housed in a building made of just about any material, and some of the older ones are quite pretty stone buildings etc.

Plant Load Factor varies widely with Hyrdo Plants because of Location and Control Method. Some large plants can produce up to 1000 Mega Watts (MW) while smaller Hyrdo Stations (About 60 - 80% or all active Hyrdo Generation is through Hydro Stations) can boost anywhere from 80 MW to 500 MW respectfully. I don't think there is a National Average but I think it's about 200 MW's. I personally factor in High Head/Low Power units because most of those locations historically do transconnect the National Grid and return, on average, about 50-100 KW's to the grid. That figure is loosely stated because we don't regulate their usage really and since we can't store power, we can only restrict it, that figure can be annually or daily. Depends on the location.

Yes, hydro come from the Greek word for water, and wave power is classed as hydro power. Other kinds of hydro power are produced from the movement of water through dams, tides and rivers.

For the time it takes to fill the dam, there'd be no flow of water downstream. Might be awkward for someone in that direction who'd been relying on that water.

Depending on size, the area upstreams of the wall will be flooded. Kinda awkward for someone using that area of land.

A dam will prevent any fish from travelling up & down the river.

Advantages:

1.) Surface water can be easily retrieved and carried in buckets

2.) Surface water stops isomorphic deterioration of the surface land below it.

3.) Surface water evaporates thus making clouds

Disadvantages:

1.) Surface water kills loads of people every month. If there were no surface water, people in major cities wouldn't have to worry about drowning every day.

2.) Surface water killed a whole load of bison. And that's terrible.

3.) Surface water provides a very easily accessible hideout for terrorists and criminals running from law enforcement officials. Breaks bullets, too, so they can't shoot at them even if they see them hiding.
