The cross-sectional area of a turboprop engine inlet in aircraft design plays a crucial role in determining the amount of air entering the engine, which is a fundamental factor for engine performance. The formula for cross-sectional area (A) can be defined
- – A is the cross-sectional area (in square meters, m²).
- – ṁ is the mass flow rate of air into the engine (in kilograms per second, kg/s).
- – ρ is the density of the air entering the engine (in kilograms per cubic meter, kg/m³).
- – V is the velocity of the air entering the engine (in meters per second, m/s).
