Air lock in pipes

Air lock in pipes

- Engineering nearly always involves assumptions and simplifications. There are just too many variables in the real world to keep track of them all, so we simplify. We neglect the variables that don't matter and we make assumptions about the variables we can't measure or predict. But what happens when one of those assumptions is wrong? One of the most basic assumptions made by engineers who design pipelines is that those pipelines only carry the fluid that's intended, but that's not always the case. Hey, I'm Grady and this is "Practical Engineering". On today's episode, we're talking about airlock in pipe systems. (upbeat music) Put simply, airlock is a constriction in flow that happens when gas gets trapped inside a pipe. That's the answer to the title of this video, but it's not very satisfying on its own, in fact, if you're as curious as I am, it just leads to more questions. The first three that come to…
