The Mass Flow Rate of an exhaust system in aircraft design refers to the amount of exhaust gases expelled by the aircraft’s engines in a given period of time. It’s a critical parameter for engine performance and emissions analysis. The formula to calculate the Mass Flow Rate (ṁ) is:
– ṁ is the Mass Flow Rate (in kilograms per second, kg/s).
– ρ is the density of the exhaust gases (in kilograms per cubic meter, kg/m³).
– A is the cross-sectional area of the exhaust nozzle (in square meters, m²).
– V is the exhaust velocity (in meters per second, m/s).
