The velocity of a throttle in aircraft design refers to the speed of the fluid (usually air or fuel) passing through the throttle. It is a critical parameter for controlling the engine’s power output.
Formula: The velocity (V) through a throttle can be calculated using the mass flow rate (ṁ) and the cross-sectional area (A) of the throttle using the equation:
- V = Velocity (in meters per second, m/s)
- 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)
