Non-dimensional velocity with respect to the Mach number is a dimensionless quantity used to express the velocity of an object or fluid flow in relation to the speed of sound within that medium. It is a common way to characterize and analyze the flow of compressible fluids, particularly in aerodynamics and fluid dynamics.
- Non-dimensional velocity (V’) in m/s
- Specific heat ratio (𝛾)
- Mach number (M)
