The mass flow rate of air entering an inverted inline piston engine in aircraft design is an important 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, m/s).
