they came around 4000 B.C for grinding grains and supplying water so humans and animals don't have to anymore.
A turbine or water wheel,
In an undershot water wheel, the wheel turns as a result of the weight of the water. The water flows into the wheel, stops and then when the wheel turns the water flows out underneath the wheel. It is used when you do not have a big head of water. In the overshot wheels the water pushes the wheel and then flows over the top of the wheel. The overshot wheel uses both the weight and the momentum of the water and so are more efficient and powerful.
Itsinfo on a water wheel
The wheel came into existence by the early men. -they used diagrams of circular objects like a potters wheel to come up with the WHEEL!!!!!!
The sumerians invented the water wheel.
If you buy it new......than yes,it comes with a wheel. If you buy it used.......than no,it does not come with a wheel.
By using the water to drive a turbine or a water wheel or pelton wheel.
Yes, Sumerians did invent the water wheel. In fact the Sumerians invented the wheel.
A water wheel with buckets is called a noria
A water wheel uses the force of flowing water to turn its blades. As the blades rotate, they transfer this mechanical energy to a shaft connected to machinery or a generator, allowing the water wheel to perform work such as grinding grain or generating electricity.
The device developed to harness the power of moving water is called a water turbine. Water turbines are mechanical devices that convert the energy from flowing or falling water into rotational mechanical energy. This energy can then be used to drive machinery or generate electricity in hydroelectric power plants. Water turbines come in various types such as Pelton, Francis, and Kaplan turbines, each designed for different water flow and head conditions.
