The velocity (\(V\)) in the context of aircraft design refers to the speed of air or exhaust gases at a specific point within an engine, such as the GE J35 engine. Velocity is a crucial parameter that affects engine performance and overall aircraft design.
The formula to calculate velocity is:
– \(V\) is the velocity of the fluid (in meters per second, m/s).
– \(\dot{m}\) 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 flow (in square meters, m²).
