The mass flow rate of exhaust in aircraft design, often referred to as “engine exhaust mass flow rate,” is a critical parameter that represents the rate at which exhaust gases are expelled from the aircraft’s engines. It is a key factor in engine performance and emissions calculations.
- ṁ = Mass flow rate (in kilograms per second, kg/s)
- ρ = Density of the fluid (in kilograms per cubic meter, kg/m³)
- A = Cross-sectional area of the turbine inlet (in square meters, m²)
- V = Inlet velocity of the fluid (in meters per second, m/s)
