The mass flow rate m of a divergence nozzle in aircraft design is the measure of how much mass or fluid passes through the nozzle per unit of time. It can be calculated using the following formula:
- m is the mass flow rate (in kilograms per second, kg/s).
- rho is the density of the fluid (in kilograms per cubic meter, kg/m³).
- A is the cross-sectional area of the nozzle (in square meters, m²).
- V is the velocity of the fluid (in meters per second, m/s).
