In the context of aircraft design, “velocity” is not directly associated with the airframe structure itself. The velocity ((V)) in aircraft design is typically used to describe the speed of the aircraft as a whole. It’s usually measured in units like meters per second (m/s) or kilometers per hour (km/h).
- ṁ represents the mass flow rate of the fluid.
- ρ is the density of the fluid.
- A is the cross-sectional area through which the fluid flows.
- V is the velocity of the fluid.
