WebFeb 12, 2024 · For a gas, the rate at which diffusion occurs is proportional to the square root of the density of the gas. The density of a gas is equal to the mass of the gas divided by the volume of the gas. If the volume is held constant one gas is compared with another with another, R 2 R 1 = M 1 M 2. where R is the rate of diffusion in mol/s and M is the ... WebMay 4, 2010 · Experimental data for the diffusivity of carbon dioxide, methane, ethane and nitrogen in Athabasca bitumen are presented in the range 25–90°C at 4 and 8 MPa. The diffusivity of these gases has been determined as a function of gas concentration in bitumen using a non-intrusive experim̀ental method. The diffusivity of gas in general is …
