Annubar

Okay kiddo, let me explain what an Annubar is!

An Annubar is a kind of tool that is used to measure the flow of fluids (like liquids or gases) in a pipe or a duct. It looks like a little stick with holes on it that is attached to the side of the pipe or duct.

When fluids move through the pipe or duct, they create pressure. The Annubar measures this pressure and uses it to calculate how fast the fluid is flowing.

Think of it like blowing up a balloon. The harder you blow, the more pressure you create in the balloon. Similarly, the faster the fluid is flowing, the more pressure it creates in the pipe or duct.

Annubars are really useful because they can measure fluid flow accurately and quickly, without slowing down or interrupting the flow. This helps engineers and scientists to make sure that things like air conditioning systems, water pipes, and even airplane engines are working the way they should.

So, that's what an Annubar is! A little stick with holes on it that measures fluid flow in pipes or ducts.
