The mass flow rate of a turboprop engine in aircraft design is a key parameter that describes the amount of air that the engine ingests and accelerates through its propeller to generate thrust. The formula for the mass flow rate (ṁ) can be defined as:
- – 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 air enters the engine (in square meters, m²).
- – V is the velocity of the air entering the engine (in meters per second, m/s).
