There are several basic properties that we use in the study of air.
They are follows
01.Pressure
The normal force per unit area exerted on a surface.
02.Density
The density of a substance is the mass of that substance per unit volume.
03.Temperature
The temperature is a measure of the average Kinetic Energy of a gas.
04.Velocity
The Displacement at a direction per time unit.
05.A streamline
A streamline is the path taken by a molecule of a gas in a steady flow situation.
06.Altitude
Height above sea level
07.Geometric Altitude
The height of the aircraft relative to the local terrain, which could range from sea level to a mountain top.
