The race leading to the water wheel on a wide stream or mill pond is called the head race (or headrace [2]), and the race leading away from the wheel is called the tail race [3] (or tailrace [2]). A mill race has many geographically specific names, such as leat, [4] lade, flume, goit, penstock. These words all have more precise definitions and ...
Leat. A leat ( / ˈliːt /; also lete or leet, or millstream) is the name, common in the south and west of England and in Wales, for an artificial watercourse or aqueduct dug into the ground, especially one supplying water to a watermill or its mill pond. Other common uses for leats include delivery of water for hydraulic mining and mineral ...
Perth Lade (also known as King's Lade) is an historic 4.5 mi (7.2 km)-long watercourse (colloquially known as a mill race) in Perth and Kinross, Scotland. Created in the 11th century or earlier, [2] it has been used to power several watermills, [3] such as those that functioned at Perth's Lower City Mills , which have existed since the 18th ...
Suspended load. The suspended load of a flow of fluid, such as a river, is the portion of its sediment uplifted by the fluid's flow in the process of sediment transportation. It is kept suspended by the fluid's turbulence. The suspended load generally consists of smaller particles, like clay, silt, and fine sands.
Long Load was recorded as ‘Lade’ in the late 12th century and ‘La Lade’ in 1285 meaning The watercourse or drainage channel from the Old English ‘lād’ or The long route (from) where goods were carried from the Old English lang and laed. It has also been suggested that the name derives from O.E. lad meaning a water-course. [2]
The Pelton wheel or Pelton Turbine is an impulse -type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [1] [2] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they ...
The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
Front-loading washers also use less water than top-load washers and require less detergent. They also spin faster than top-loaders, extracting more water from clothes, which reduces drying time.
