A water wheel in Erlangen, Germany The reversible water wheel powering a mine hoist in De re metallica (Georgius Agricola, 1566) The sound of the Otley waterwheel, at Manchester Museum of Science and Industry. A water wheel is a machine for converting the kinetic energy of flowing or falling water into useful forms of power, often in a watermill.
The norias discharge water into aqueducts built on tall stone arches. To catch the water, each aqueduct has a very short section parallel to the water wheel and the river. This joins at 90 degrees the main section of the aqueduct, which leads away from the river and was sometimes many hundreds of metres long. [12]
The undershot water wheel and overshot water wheel, both animal- and water-driven, and with either a compartmented body (Latin tympanum) or a compartmented rim, were used by Hellenistic engineers between the 3rd and 2nd century BC. [11] In 1st century BC, Roman architect Vitruvius described the function of the noria. [12]
The water falls from the pipe into the buckets (formed from wooden slats on the circumference) and makes the wheel rotate in what is described as the 'reverse' direction: it is a backshot wheel. The crank has a throw of 4 feet (1.2 m) and connects to a counterweight and to a very long rod.

A watermill or water mill is a mill that uses hydropower.It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering.
These include all three variants of the vertical water wheel as well as the horizontal water wheel. [6] Apart from its main use in grinding flour, water-power was also applied to pounding grain, [7] crushing ore, [8] sawing stones [9] and possibly fulling and bellows for iron furnaces. [10]
The estimated cost to build one water wheel is $1.9 million, and the city has yet to meet its goal. Donations from sponsors and partnerships total $1.34 million.
Pelton patented his wheel as well as his novel design of the double cup runner, and in 1888 formed the Pelton Water Wheel Company in San Francisco to supply the growing demand for hydropower and hydroelectricity throughout the West and world-wide. [6] 'Pelton' is a trademark name for the products of that company, but the term is widely used ...
