Fig. 2. Mass flow (a) and mass flow ratio (b). The mass flow for the two flow directions, m?A and m?B, MDV3100 made dimensionless with the isothermal purely free molecular flow of the gaseous phase, m?gas,Knudsen. The ratio m?A/m?B is shown in (b). Numbers in circles mark values of p1/psatp1/psat referred to in Fig. 3.Figure optionsDownload full-size imageDownload as PowerPoint slide

For p1=psatp1=psat, the mass flux of m?B≈50m?gas,Knudsen corresponds to m?B≈400 g/(m2m2 s). For marine biome value, the Eckert-number in the free space downstream of the membrane is about 1.5×10-61.5×10-6 and the Mach-number, also in the free space, is about 2×10-42×10-4.
