  2. Suction pressure - Wikipedia

    en.wikipedia.org/wiki/Suction_pressure

    In refrigeration and air conditioning systems, the suction pressure' (also called the low-side pressure) is the intake pressure generated by the system compressor while operating. The suction pressure, along with the suction temperature the wet bulb temperature of the discharge air are used to determine the correct refrigerant charge in a system.

  3. Suction - Wikipedia

    en.wikipedia.org/wiki/Suction

    Suction is the day-to-day term for forces experienced by objects that are exposed to the movement of gases or liquids moving along a pressure gradient. Contrary to popular belief, however, the forces acting in this case do not originate from the lower pressure side (the vacuum), but from the side of the higher pressure.

  4. Vacuum ejector - Wikipedia

    en.wikipedia.org/wiki/Vacuum_Ejector

    In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area. The fluid leaving the jet is flowing at a high velocity which due to Bernoulli's principle results in it having low pressure, thus generating a vacuum. The outer tube then narrows into a mixing ...

  5. Vacuum - Wikipedia

    en.wikipedia.org/wiki/Vacuum

    Suction can spread and dilute a vacuum by letting a higher pressure push fluids into it, but the vacuum has to be created first before suction can occur. The easiest way to create an artificial vacuum is to expand the volume of a container. For example, the diaphragm muscle expands the chest cavity, which causes the volume of the lungs to ...

  6. Draft (water) - Wikipedia

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

    A suction pump creates a partial vacuum (a "draft") and the atmospheric pressure on the water's surface forces the water into the pump, usually via a rigid pipe (sometimes called a dry hydrant) or a semi-rigid hard suction hose. [1] [2]

  7. Venturi effect - Wikipedia

    en.wikipedia.org/wiki/Venturi_effect

    Water aspirators produce a partial vacuum using the kinetic energy from the faucet water pressure; Steam siphons use the kinetic energy from the steam pressure to create a partial vacuum; Atomizers disperse perfume or spray paint (i.e. from a spray gun or airbrush) Carburetors use the effect to suck gasoline into an engine's intake air stream

  8. Orders of magnitude (pressure) - Wikipedia

    Pressure due to direct impact of a strong breeze (~28 mph or 45 km/h) [27] [28] [31] 120 Pa Pressure from the weight of a U.S. quarter lying flat [32] [33] 133 Pa 1 torr ≈ 1 mmHg [34] ±200 Pa ~140 dB: Threshold of pain pressure level for sound where prolonged exposure may lead to hearing loss [citation needed] ±300 Pa ±0.043 psi

  9. Suction cup - Wikipedia

    en.wikipedia.org/wiki/Suction_cup

    A transparent suction cup The pressure on a suction cup, as exerted by collisions of gas molecules, holds the suction cup in contact with the surface. One cup suction lifter. A suction cup, also known as a sucker, is a device or object that uses the negative fluid pressure of air or water to adhere to nonporous surfaces, creating a partial ...
