WebImaging of dye diffusion over time allowed for the comparison of mass transport rates under a series of rotation per minute (RPM) speeds for the High Aspect Ratio Vessels (HARVs) on a Rotating Wall Vessel (RWV). This was done to determine the speed that will most accurately simulate the low convective rates experienced under actual µg conditions. WebCarbon dioxide (relative molecular mass 44) is about one and a half times denser than air (average relative molecular mass about 29), and mixing of gases of differing densities by diffusion can be a slow process unless the mixture is deliberately stirred. Hence gases can be effectively poured from one vessel to another, and also of course be ...
