In aerodynamics, the term “hydrostatic equation” typically refers to a simplified form of the hydrostatic pressure equation that applies to the atmosphere. It is also known as the barometric or barometric pressure equation. The hydrostatic equation in aerodynamics is used to describe the relationship between pressure, altitude, and gravity in the Earth’s atmosphere.
- p: Pressure at a certain depth in the fluid
- ρ: Density of the fluid
- gs: Sea level acceleration due to gravity
- dh: Height difference between two points in the fluid
