  2. Flash evaporation - Wikipedia

    en.wikipedia.org/wiki/Flash_evaporation

    If the throttling valve or device is located at the entry into a pressure vessel so that the flash evaporation occurs within the vessel, then the vessel is often referred to as a flash drum. [1] [2] If the saturated liquid is a single-component liquid (for example, propane or liquid ammonia), a part of the liquid immediately "flashes" into vapor.

  3. Joule–Thomson effect - Wikipedia

    en.wikipedia.org/wiki/Joule–Thomson_effect

    [7] [8] In hydraulics, the warming effect from Joule–Thomson throttling can be used to find internally leaking valves as these will produce heat which can be detected by thermocouple or thermal-imaging camera. Throttling is a fundamentally irreversible process. The throttling due to the flow resistance in supply lines, heat exchangers ...

    en.wikipedia.org/wiki/Science_project

    A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.

    A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.

    CPU throttling, computer hardware speed control, also known as dynamic frequency scaling; Bandwidth throttling, used to control the bandwidth that a network application can use; Throttling process (computing), software speed control

  7. Throttle - Wikipedia

    en.wikipedia.org/wiki/Throttle

    Throttling of a rocket engine means varying the thrust level in-flight. This is not always a requirement; in fact, the thrust of a solid-fuel rocket is not controllable after ignition, and is instead pre-planned by varying the shape of the void down the center of the booster when the fuel is molded.

  8. Sleeve valve (water) - Wikipedia

    en.wikipedia.org/wiki/Sleeve_valve_(water)

    A sleeve valve is a device typically used in a water supply or distribution system when there is a need to reduce high pressure or throttle flow. The sleeve valve consists of a cylindrical gate (tube) which slides over an inner sleeve.

    A diagram of the device. Newman's Energy Machine was a DC motor which the inventor, Joseph Newman, claimed to produce mechanical power exceeding the electrical power being supplied to it. In 1979, Newman attempted to patent the device, but it was rejected by the United States Patent Office as being a perpetual motion machine. [1]
