  2. Paddle wheel - Wikipedia

    en.wikipedia.org/wiki/Paddle_wheel

    The paddle wheel is a device for converting between rotary motion of a shaft and linear motion of a fluid. In the linear-to-rotary direction, it is placed in a fluid stream to convert the linear motion of the fluid into rotation of the wheel. Such a rotation can be used as a source of power, or as an indication of the speed of flow.

  3. Water aeration - Wikipedia

    en.wikipedia.org/wiki/Water_aeration

    Coarse bubble aeration is a type of subsurface aeration wherein air is pumped from an on-shore air compressor. [ 6 ] through a hose to a unit placed at the bottom of the water body. The unit expels coarse bubbles (more than 2mm in diameter), [ 7 ] which release oxygen when they come into contact with the water, which also contributes to a ...

    en.wikipedia.org/wiki/Raceway_pond

    Raceway pond used for the cultivation of microalgae. The water is kept in constant motion with a powered paddle wheel. A raceway pond is a shallow artificial pond used in the cultivation of algae. [1] [2] The pond is divided into a rectangular grid, with each rectangle containing one channel in the shape of an oval, like an automotive raceway ...

  5. Aeration - Wikipedia

    en.wikipedia.org/wiki/Aeration

    Aeration (also called aerification or aeriation) is the process by which air is circulated through, mixed with or dissolved in a liquid or other substances that act as a fluid (such as soil). Aeration processes create additional surface area in the mixture, allowing greater chemical or suspension reactions.

  6. Soil aeration - Wikipedia

    en.wikipedia.org/wiki/Soil_aeration

    Soil aeration is the mechanism of improving the exchange of gases between the atmosphere and soil. Through soil microbial activity and plant root respiration, certain gases such as oxygen will be depleted in the soil, while others, such as carbon dioxide, will build up in the soil. [1] Lack of oxygen in the soil can impact plant growth.

    New York’s surging migrant growth has seen the state’s population tick up between 2023 and 2024, reversing a years-long trend as locals leave the state for cheaper living or warmer weather.

  8. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    Paddle wheel flowmeters (also known as Pelton wheel sensors) consist of three primary components: the paddle wheel sensor, the pipe fitting and the display/controller. The paddle wheel sensor consists of a freely rotating wheel/impeller with embedded magnets which are perpendicular to the flow and will rotate when inserted in the flowing medium.
