The mass flow rate of a throttle in aircraft design represents the amount of air or fuel passing through the throttle per unit of time. It is often used to control the engine’s power output.
Formula: The mass flow rate (ṁ) through a throttle can be calculated using the equation:
- ṁ = Mass flow rate (in kilograms per second, kg/s)
- A = Cross-sectional area of the throttle opening (in square meters, m²)
- ρ = Density of the fluid (air or fuel) passing through the throttle (in kilograms per cubic meter, kg/m³)
- V = Velocity of the fluid passing through the throttle (in meters per second, m/s)
