[00:00:00]We know what is atmosphere. We know what is the physical property of air, but today we're going to focus on one property, the pressure. [music] We know that the pressure is the force exerted by air per unit area. But today, we have to understand something important. In the air, we have two kind of pressure.

[00:00:20]We have static pressure and dynamic pressure. And [music] today we're going to know the difference of both pressure.

[00:00:26]Let's start.

[00:00:28]Static pressure is the pressure of air at rest. And static pressure decreases with altitude. [music] Meaning that for higher altitude, we have lower static pressure. And for lower altitude, we have higher static pressure. And static pressure is measured [music] by static wand. And this static wand is fixed on the fuselage. What about dynamic pressure?

[00:00:52]Dynamic pressure is the pressure [music] created by the motion of air. It represent the kinetic energy of moving air. This is >> [music] >> the formula. Another thing that we have to know is when an aircraft is flying, the air flow has dynamic pressure and static pressure. And the total pressure is measured by pitot tube. And this is the formula of total pressure. So, to conclude, static pressure depend on altitude and dynamic pressure depend on speed.
