A demonstration and brief explanation of air lock in fluid pipelines. If you assume that gasses don’t get into pipes or that they can’t constrict the flow, you might design a pipeline that doesn’t work. Luckily for engineers, this is a well-known phenomenon in pipe systems. It’s just one of the complexities that come with the job and we’ve come up a with a lot of creative ways to overcome it.
