In the chapter Mechanics of Fluids and Gases, we deal with the description of the equilibrium and movement of fluids. In this lesson, we will focus on the pressure in gases, which is caused by the atmospheric pressure force. First, we will review the concept of pressure, then we will look at the Earth's atmosphere and its layers (troposphere, stratosphere, mesosphere, thermosphere, exosphere), we will introduce the Kármán limit. Next, we will talk about how atmospheric pressure changes with altitude and what affects it, we will introduce the instruments used to measure it (barograph, barometer, aneroid). We will introduce what normal atmospheric pressure is. We will also show its use and calculate some examples, and finally we will come to an interesting point.
