  2. Bottled gas - Wikipedia

    en.wikipedia.org/wiki/Bottled_gas

    The general rule is that one unit volume of liquid will expand to approximately 800 unit volumes of gas at standard temperature and pressure with some variation due to intermolecular force and molecule size compared to an ideal gas. Normal high pressure gas cylinders will hold gas at pressures from 200 to 400 bars (3,000 to 6,000 psi). An ideal ...

  3. Gas cylinder - Wikipedia

    en.wikipedia.org/wiki/Gas_cylinder

    A gas cylinder quad, also known as a gas cylinder bundle, is a group of high pressure cylinders mounted on a transport and storage frame. There are commonly 16 cylinders, each of about 50 litres capacity mounted upright in four rows of four, on a square base with a square plan frame with lifting points on top and may have fork-lift slots in the ...

    P 2 and V 2 the initial pressure and volume of the other cylinder and P 3 is the equilibrium pressure. An example could be a 100-litre (internal volume) cylinder (V 1) pressurised to 200 bar (P 1) filling a 10-litre (internal volume) cylinder (V 2) which was unpressurised (P 2 = 1 bar) (resulting in both cylinder equalising to approximately 180 ...

  5. Volumetric efficiency - Wikipedia

    en.wikipedia.org/wiki/Volumetric_efficiency

    It also denotes the ratio of equivalent air volume drawn into the cylinder to the cylinder's swept volume. [5] This equivalent volume is commonly inserted into a mass estimation equation based upon Boyle's Gas Law. When VE is multiplied by the cylinder volume, an accurate estimate of cylinder air mass (charge) can be made for use in determining ...

  6. Standard cubic foot - Wikipedia

    en.wikipedia.org/wiki/Standard_cubic_foot

    For petroleum gases, the standard cubic foot (scf) is defined as one cubic foot of gas at 60 °F (288.7 K; 15.56 °C) and at normal sea level air pressure. The pressure definition differs between sources, but are all close to normal sea level air pressure. A pressure of 14.696 pounds per square inch (1.00000 atm; 101.325 kPa). [2]

  7. Industrial gas - Wikipedia

    en.wikipedia.org/wiki/Industrial_gas

    A gas compressor is used to compress the gas into storage pressure vessels (such as gas canisters, gas cylinders or tube trailers) through piping systems. Gas cylinders are by far the most common gas storage [29] and large numbers are produced at a "cylinder fill" facility. However, not all industrial gases are supplied in the gaseous phase.

  8. Specific volume - Wikipedia

    en.wikipedia.org/wiki/Specific_volume

    For a substance X with a specific volume of 0.657 cm 3 /g and a substance Y with a specific volume 0.374 cm 3 /g, the density of each substance can be found by taking the inverse of the specific volume; therefore, substance X has a density of 1.522 g/cm 3 and substance Y has a density of 2.673 g/cm 3. With this information, the specific ...
