Water Mills were one of the first mechanical devices to utilise renewable energy sources. Water wheels were built on the fast-flowing rivers or streams, which were constructed to control water levels and flow speed.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">What is a water wheel?\u00a0<\/span><\/strong><\/p>\n<p><span data-preserver-spaces=\"true\">A device that converts the energy of flowing water into proper forms of power, often in a watermill. It consists of a wheel with a few blades and buckets arranged outside.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Almost all wheels work by water from a millpond, formed when obstructed by a flowing stream.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">Mill race\u00a0<\/span><\/strong><span data-preserver-spaces=\"true\">is a channel for the water flowing to or from a water wheel.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">Headrace\u00a0<\/span><\/strong><span data-preserver-spaces=\"true\">is the channel bringing water from the mill pond to the water wheel.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">A tailrace\u00a0<\/span><\/strong><span data-preserver-spaces=\"true\">carries water after it has left the wheel.\u00a0<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Water wheels were first used in ancient times, and they became widespread in the Middle Ages. The wheel power of standing water is transferred to the upright shaft that rotates the millstone inside the mill by gears and shaft extending from the axle. The millstones are placed in casings on the top floor of mills. Then, with the help of a hopper, grains are fed into them, including the use of shafts or slides, the ground material is transferred into the storage chests.\u00a0<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Water wheels were most commonly used in green mills, but they were also found in iron forges, sawmills and mines.<\/span><\/p>\n<p><strong><span data-preserver-spaces=\"true\">Advantages of waterwheel:<\/span><\/strong><\/p>\n<ul>\n<li><span data-preserver-spaces=\"true\">It has a high moment of inertia, making it suitable for direct drive of slowly-rotating machines and machines with alternate resistance.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Waterwheels have a simple hydraulic design and construction.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">They are suitable for small, highly alternating water quantities.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Well constructed water wheels have up to 80% rate of efficiency.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">They have low maintenance expenditures, are very easy to repair, and have a long lifespan.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Water wheels have a good storage of water and therefore producing energy is possible with the help of reservoirs.<\/span><\/li>\n<\/ul>\n<p><strong><span data-preserver-spaces=\"true\">Disadvantages of water wheel:<\/span><\/strong><\/p>\n<ul>\n<li><span data-preserver-spaces=\"true\">They are heavy and have a large space requirement, as well as there are losses with overshot wheels due to the height and suspension.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">The rotational speed should be as low as possible to avoid fast emptying of the scoops due to greater centrifugal forces.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">A high and good initial torque is required. Water wheels are gravity machines and are more efficient than turbines when well constructed. The conversion into other forms of energy is quite difficult or impossible due to the low rotational operating speed.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">The long-distance transference of the energy by water wheels is not possible.<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">They do require expensive hydrological construction measures. Due to this, utilisation of hydromechanical energy may not be possible.<\/span><\/li>\n<\/ul>\n<p><span data-preserver-spaces=\"true\">At last, water wheels fit the best for application in small-scale mining due to the number of possibilities to use them in the direct mechanical drive of various mining and mineral extracting machines. Moreover, despite the relatively high investment costs, the water wheels are effortless to manufacture locally using domestic construction materials. Also, they are distinguished by low maintenance and repair costs.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>People use natural sources of energy to complement human and animal work power.
