In aircraft design, the mass flow rate of the airframe is typically a parameter that’s commonly used, as the airframe itself isĀ a substance or component through which mass flows. Instead, the term “mass flow rate” is commonly used to describe the flow of air, fuel, or other substances through various components or systems within an aircraft.
- į¹ is the mass flow rate in kilograms per second (kg/s).
- Ļ is the air density in kilograms per cubic meter (kg/mĀ³).
- A is the cross-sectional area of Airframe (in square meters, mĀ²).
- V is the velocity of the Airframe (in meters per second, m/s).
