Question

Define water energy and provide some samples of it ?

Answer 1

Hint: Energy is that quantitative property that has got to be transferred to an object so as to perform work on, or to heat, the thing . Energy is a conserved quantity;so, the law of conservation of energy states that energy is often converted in form, but not created or destroyed.

Complete answer:
Water energy is often defined because the energy that's derived from water, generally through its motion. A standard example of water energy is hydroelectricity, which derives power from the water that flows over dams. Another important example of water energy is that the energy that's harnessed from the tides (also referred to as tidal energy).

The K.E. of flowing water is usually mentioned as hydraulic energy. This hydraulic energy is converted into energy (for the movement of certain mechanical devices), then into electricity (usually with the assistance of rotating turbines).

Typically, water energy is harnessed by making an outsized volume of water be due a better altitude to a lower altitude (the momentum gained by the water as a consequence of the gravitational forces working on it's harnessed and converted into usable energy). Water energy may be a clean, renewable source of energy.

Note: Water energy resources include hydroelectric power from lakes and rivers, ocean energy in its various forms, and energy technologies that cash in of saline water.Hydropower makes use of the K.E. water gains when it drops in elevation.
