What else can I help you with?
How available is hydroelectricity?
unlimited, as long as you have water and a dam
What is the difference between a small dam and a large one?
The large dam is larger...pretty self explanatory. Also the larger dam will be heavier, take up more space, stop more water, and lots more.
What is sometimes build to control the flow of moving surface water?
Dam if I know. Sorry couldn't resist. It is a dam that crosses rivers to control the water flow. Dam's come in all sizes, shapes, and materials. One of the largest dams in the world is the Aswan dam that crosses the Nile River. It's a huge edifice made of cement and steel. Probably the smallest dams are the ones built by beavers. They use gnawed off branches and trees to block up small streams. Lots of man-made dams are built to provide hydro-electric power for the regional area. Hoover Dam in Nevada USA is such a dam. Others are built to provide flood control so that areas downstream don't get flooded out during heavy rainstorms for example. The Aswan Dam is both a flood control and power providing dam.
How can Electricity be generated from water trapped behind a dam?
Hydroelectricity or some people call it hydropower. all electricity is the same. hydroelectricity is given its name because of the use of water in the process of making the electricity.
What does hydroelectric power use?
Hydroelectricity is the use of water. Water flows through a turbine in a dam, which spins it creating kinetic energy, this is then transferred into electrical energy
The what energy of water in a dam is increased by raising the level of water behind the dam?
Potential Energy
How is water in a dam increased?
rainwater
Why the base of the dam is made wider?
The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.
Type of river dam used to raise the water level?
Any dam will raise the water level behind it.
What is the causes of shortage of water?
The country has been experiencing an extremely hot weather recently and even it rained on the Chap Goh Meh, the rains poured with pollutants and it did not help much in raising dam's water level. The water level has reached a record low
What are the barrages and why were they built?
A barrage is a type of dam that uses gates to control the level of water. They were built to divert water or to dam a lagoon.
What is current water level of Narmada dam?
8 tmc
What is current water level of ujani dam percentage?
50.68TMC
How might the potential energy of water in a dam be increased?
By filling the dam with more water, because by doing that it gains more gravitational potential energy which is the same as potential energy.
What is current water level of Jayakwadi dam?
approximately 20 TMC
How energy from sun is stored in water behind dam?
Solar energy is absorbed by the sun-warmed water in the reservoir behind the dam. This heat energy increases the temperature of the water, raising its potential energy. When the water is released through turbines in the dam, this potential energy is converted into kinetic energy, which drives the turbines to generate electricity.
What is present percentage of water level at allemanskraal dam in South Africa?
49%
