In aircraft design, the Cross-Sectional Area of an exhaust system refers to the area through which exhaust gases exit the engine. This area is significant for understanding the exhaust flow and pressure. The formula to calculate the cross-sectional area (A) is:
– A is the cross-sectional area of the exhaust nozzle (in square meters, m²).
– ṁ is the Mass Flow Rate of exhaust gases (in kilograms per second, kg/s).
– ρ is the density of the exhaust gases (in kilograms per cubic meter, kg/m³).
– V is the exhaust velocity (in meters per second, m/s).
