WebbThe overshot wheel solves this problem by bringing the water flow to the top of the wheel. The water fills buckets built into the wheel, rather than the simple paddle wheel design … WebbThe pitchback also needs a slightly more complex water supply arrangement directly above the wheel, known as a penstock, to build up a small head of perhaps 2 ft.

Webbback pitch: [noun] the center-to-center distance between two parallel rows of rivets in riveted joints. A backshot wheel (also called pitchback) is a variety of overshot wheel where the water is introduced just before the summit of the wheel. In many situations, it has the advantage that the bottom of the wheel is moving in the same direction as the water in the tailrace which makes it more efficient. Visa mer A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel (usually constructed from wood or metal), with a number of Visa mer As in all machinery, rotary motion is more efficient in water-raising devices than oscillating motion. In terms of power source, waterwheels … Visa mer The energy available to the wheel has two components: • Kinetic energy – depends on how fast the water is moving when it enters the wheel • Potential energy – … Visa mer • Hydroelectricity • Watermill • Water turbine • Pelton wheel Visa mer Water wheels come in two basic designs: • a horizontal wheel with a vertical axle; or • a vertical wheel with a horizontal axle. The latter can be … Visa mer Overshot (and particularly backshot) wheels are the most efficient type; a backshot steel wheel can be more efficient (about 60%) than all but the most advanced and well-constructed turbines. In some situations an overshot wheel is preferable to a turbine. Visa mer ^ Dotted notation. A dot above the quantity indicates that it is a rate.
