This website includes an animation which shows the stages that molecules go through as they move from the turbulent stage of viscous flow, transition into laminar flow, and then transition again into molecular flow. You may pause this animation between stages. Objective: Identify the five stages of flow. This simulation is from Module 98 of the Vacuum Technology and Gas Control Cluster of the MATEC Module Library (MML). You can find this animation under the section "Vacuum Technology & Gas Controls."
