  2. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    The volume flow is obtained by multiplying the measured average fluid flow velocity by the inner pipe cross-section. This reference flow value is compared with the simultaneous flow value given by the flow measurement to be calibrated.

  3. Volume - Wikipedia

    en.wikipedia.org/wiki/Volume

    Some SI units of volume to scale and approximate corresponding mass of water. To ease calculations, a unit of volume is equal to the volume occupied by a unit cube (with a side length of one). Because the volume occupies three dimensions, if the metre (m) is chosen as a unit of length, the corresponding unit of volume is the cubic metre (m 3).

  4. Compressibility - Wikipedia

    en.wikipedia.org/wiki/Compressibility

    In thermodynamics and fluid mechanics, the compressibility (also known as the coefficient of compressibility [1] or, if the temperature is held constant, the isothermal compressibility [2]) is a measure of the instantaneous relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.

  5. Eudiometer - Wikipedia

    en.wikipedia.org/wiki/Eudiometer

    The electric spark can initiate a reaction in the gas mixture and the graduation on the cylinder can be read to determine the change in volume resulting from the reaction. The use of the device is quite similar to the original barometer , except that the gas inside displaces some of the liquid that is used.

    First, the change in volume of the chest is computed. The initial pressure of the box times its volume is considered equal to the known pressure after expansion times the unknown new volume. Once the new volume is found, the original volume minus the new volume is the change in volume in the box and also the change in volume in the chest.

  9. Titer - Wikipedia

    en.wikipedia.org/wiki/Titer

    Titer (American English) or titre (British English) is a way of expressing concentration. [1] Titer testing employs serial dilution to obtain approximate quantitative information from an analytical procedure that inherently only evaluates as positive or negative.
