Meaning and Definition
A large waterwheel, usually undershot or overshot, designed to power mills, factories, or machinery by harnessing the energy of flowing water.
In historical engineering contexts, a breast wheel is a type of waterwheel where the water strikes the wheel at or near its axis, as opposed to the top (overshot) or bottom (undershot). It represents an intermediate and efficient design for moderate water heads and flows.

You might see one at a preserved historical industrial site, such as an old flour mill, forge, or textile mill that is now a museum.
Yes, for moderate water heads (the height the water falls), the breast wheel was more efficient than an undershot wheel and often more practical to build than a tall overshot wheel, making it a popular choice in many 18th and 19th-century industrial applications.
A large waterwheel, usually undershot or overshot, designed to power mills, factories, or machinery by harnessing the energy of flowing water.
