The concept of “cross-sectional area” is typically applied to the weight of an aircraft in aircraft design. Cross-sectional area is usually associated with the area of a section or profile of an object, like the cross-sectional area of an aircraft wing, fuselage, or other components. It’s used to calculate parameters like aerodynamic drag or lift.
- ṁ is the mass flow rate in kilograms per second (kg/s).
- ρ is the air density in kilograms per cubic meter (kg/m³).
- A is the cross-sectional weight of the Aircraft (in square meters, m²).
- V is the velocity of the weight of the Aircraft (in meters per second, m/s).
