Initially, the gas density leaving VB2 (MV2) is lower than the gas density in the upper part of Vessel 2 (Figure 5) but later the gas density becomes higher (mark B) than the gas in the top of Vessel 2 and the density becomes even higher than the density in the upper part of Vessel 1 (mark C).

where [rho] is the gas density (kg/[m.sup.3]), u is the gas velocity vector (m/s), [C.sub.i] is the mass fraction of species i (--), [D.sub.i,m] is the molecular diffusivity of species i ([m.sup.2]/s), [[mu].sub.t] is the turbulent viscosity (kg/m x s), S[c.sub.t] is the turbulent Schmitt number (= 0.7 for gases), and [R.sub.i] is the net rate of production by chemical reaction (kg/[m.sup.3] x s).

The relationship between diffusion and gas density is clearly observed in Graham's Diffusion Law, which states that diffusion velocity is inversely proportional to the square root of gas density (Cremasco, 2002).

Helium iso-flow studies
On entering the surrounding cooler air of the atmosphere, the hot gas begins to cool as it rises, which progressively reduces the gas volume, with a proportional increase in the gas density.
