The throat area of the nozzle is a key parameter. It’s the minimum cross-sectional area within the nozzle and is typically a critical design factor.
The formula for calculating the throat area is:
- A_t is the throat area in square meters (m²).Mass Flow Rate is the rate at which mass flows through the nozzle per unit of time, typically measured in kilograms per second (kg/s).
- Exit Velocity is the velocity of the exhaust gases as they exit the nozzle, typically measured in meters per second (m/s).
- Exhaust Gas Density is the density of the exhaust gases, typically measured in kilograms per cubic meter (kg/m³).
