Mach number
- In fluid dynamics, the Mach number (M or Ma) (; German: [max]) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound.
In the following, a new nondimensional-velocity ratio, namely the critical-velocity ratio (or critical Mach number), will be derived not only to achieve this objective but also to be a tool..צפה במאמר
