In the context of aircraft design, the mass flow rate of the airframe system is typically defined by a specific formula, as it depends on various factors such as the aircraft’s design, dimensions, and operating conditions.Mass Flow Rate (ṁ): The mass flow rate represents the mass of a substance (in this case, air) passing through a system per unit of time. It’s typically expressed in units like kilograms per second (kg/s)
- 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 area through which Airframe System (in square meters, m²).
- V is the velocity of the Airframe System (in meters per second, m/s).
