Mach Number From Static Pressure Calculator

The Mach number is a dimensionless unit used to represent the speed of an object moving through a fluid, such as air or gas. In subsonic flows (M < 1), the compressibility effects are typically small, and the static pressure changes are relatively gradual with increasing Mach number. Mathematically, it is expressed as:

where:

• $M$ is the Mach number,
• $q$ is the dynamic pressure,
• $\gamma$ is the heat capacity ratio,
• P0​ is the static pressure.
