The mass flow rate of the nozzle in aircraft design, often referred to as “nozzle mass flow rate,” represents the rate at which a fluid or substance passes through the nozzle. In the context of aircraft design, this can be the rate at which exhaust gases or fuel pass through a nozzle.The formula to calculate the mass flow rate of the nozzle (ṁ_nozzle) is as follows:
- ṁ = Mass flow rate of the nozzle (in kilograms per second, kg/s)
- ρ = Density of the fluid or substance passing through the nozzle (in kilograms per cubic meter, kg/m³)
- A = Cross-sectional area of the nozzle (in square meters, m²)
- V = Velocity of the fluid or substance passing through the nozzle (in meters per second, m/s)
