Critical Mach number calculator

The critical Mach number is the velocity at which the airflow over an object or airfoil reaches the speed of sound. It’s a significant parameter in aerodynamics because it marks the boundary between subsonic and supersonic flow regimes.

Where:

  • is the critical Mach number,
  • is the specific heat ratio (ratio of specific heats),
  • is the specific gas constant,
  •  is the reference temperature.
