  2. Tidal volume - Wikipedia

    en.wikipedia.org/wiki/Tidal_volume

    Tidal volume (symbol V T or TV) is the volume of air inspired and expired with each passive breath. [1] It is typically assumed that the volume of air inhaled is equal to the volume of air exhaled such as in the figure on the right. In a healthy, young human adult, tidal volume is approximately 500 ml per inspiration at rest or 7 ml/kg of body ...

    TLC: Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.)

  4. Lung volumes and capacities - Wikipedia

    en.wikipedia.org/wiki/Lung_volumes_and_capacities

    The average total lung capacity of an adult human male is about 6 litres of air. [1] Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath. The average human respiratory rate is 30–60 breaths per minute at birth, [2] decreasing to 12–20 breaths per minute ...

  5. Tidal atlas - Wikipedia

    en.wikipedia.org/wiki/Tidal_atlas

    To calculate the rate at an intermediate tide between neap and spring, interpolation is required. Traditionally this has been done using a "calculation of rates" chart found inside tidal atlases. [5] An alternative to a tidal atlas is a nautical chart that provides tidal diamonds.

  6. Deltar - Wikipedia

    en.wikipedia.org/wiki/Deltar

    An engineer configuring the connection table on the Deltar (1984) The Deltar's 120 computing modules (1967) A computing module from the Deltar analogue computer The Deltar was an advanced system designed for simulating tides and analysing river environments by converting tidal data, river flows, and environmental factors into electrical analogue signals.

  7. Theory of tides - Wikipedia

    en.wikipedia.org/wiki/Theory_of_tides

    High and low tide in the Bay of Fundy. The theory of tides is the application of continuum mechanics to interpret and predict the tidal deformations of planetary and satellite bodies and their atmospheres and oceans (especially Earth's oceans) under the gravitational loading of another astronomical body or bodies (especially the Moon and Sun).

  8. Chart datum - Wikipedia

    en.wikipedia.org/wiki/Chart_datum

    A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW). In non-tidal areas, e.g. the Baltic Sea, mean sea level (MSL) is used. [2] A chart datum is a type of vertical datum and must not be confused ...

  9. Amphidromic point - Wikipedia

    en.wikipedia.org/wiki/Amphidromic_point

    Tides are generated as a result of gravitational attraction by the Sun and Moon. [8] This gravitational attraction results in a tidal force that acts on the ocean. [8] The ocean reacts to this external forcing by generating, in particular relevant for describing tidal behaviour, Kelvin waves and Poincaré waves (also known as Sverdrup waves). [8]
