Gaseous nitrogen
Compressed Gas Association (CGA) recommends three different connec-tions for nitrogen, depending on the pressure of the container. In addition, a high-integrity connection known also as a Diameter Index Safety System (DISS) connection has also been assigned to nitrogen. Cylinders containing nitrogen at pressures up to 3,000 psig use a CGA 580 ...

14.14: Dalton's Law of Partial Pressures
The total pressure of the gas mixture is equal to the sum of the individual pressures. If P1 = 300 mm Hg P 1 = 300 mm Hg and P2 = 500mm Hg P 2 = 500 mm Hg, then Ptotal = 800mm Hg P total = 800 mm Hg. Figure 14.14.1 14.14. 1: Dalton's law says that the pressure of a gas mixture is equal to the partial pressures of the combining gases.
