The mass flow rate of the exhaust nozzle in aircraft design, also known as “exhaust nozzle mass flow rate,” is a critical parameter that represents the rate at which exhaust gases exit the aircraft’s engine nozzle. It is a key factor in engine performance and emissions calculations.The formula to calculate the mass flow rate of the exhaust nozzle (ṁ_nozzle) is as follows:
- ṁ = Mass flow rate of the exhaust nozzle (in kilograms per second, kg/s)
- ρ = Density of the exhaust gases at the nozzle (in kilograms per cubic meter, kg/m³)
- A = Cross-sectional area of the exhaust nozzle (in square meters, m²)
- V = Velocity of the exhaust gases at the nozzle (in meters per second, m/s)
