The cross-sectional area A of a convergence nozzle in aircraft design can be defined as the area through which a fluid flows as it passes through the nozzle. In a convergent nozzle, the cross-sectional area decreases in the direction of flow. The formula to calculate the cross-sectional area is given by:
- A is the cross-sectional area of the nozzle (in square meters, m²).
- m is the mass flow rate of the fluid (in kilograms per second, kg/s).
- rho is the density of the fluid (in kilograms per cubic meter, kg/m³).
- V is the velocity of the fluid (in meters per second, m/s).
