2. 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 ...

3. 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 ...

4. Graduated cylinder - Wikipedia

   en.wikipedia.org/wiki/Graduated_cylinder

   For accuracy the volume on graduated cylinders is depicted on scales with 3 significant digits: 100mL cylinders have 1ml grading divisions while 10mL cylinders have 0.1 mL grading divisions. Two classes of accuracy exist for graduated cylinders. Class A has double the accuracy of class B. [4] Cylinders can have single or double scales. Single ...

5. Diving cylinder - Wikipedia

   en.wikipedia.org/wiki/Diving_cylinder

   The nominal volume of gas stored is commonly quoted as the cylinder capacity in the USA. It is a measure of the volume of gas that can be released from the full cylinder at atmospheric pressure. [40] Terms used for the capacity include 'free gas volume' or 'free gas equivalent'. It depends on the internal volume and the working pressure of a ...

6. Propane - Wikipedia

   en.wikipedia.org/wiki/Propane

   A 20 lb (9.1 kg) steel propane cylinder. This cylinder is fitted with an overfill prevention device (OPD) valve, as evidenced by the trilobular handwheel. Propane (/ ˈ p r oʊ p eɪ n /) is a three-carbon alkane with the molecular formula C 3 H 8. It is a gas at standard temperature and pressure, but compressible to a

   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 ...
