The mass flow rate of air entering an inline piston engine in aircraft design is a key parameter that defines the amount of air the engine ingests. The formula for 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
