Frequently Asked Questions

How do you calculate Mach?

How to Calculate the Mach Number. The formula for the speed of sound is, Speed of Sound, a = squareroot (gamma*R*T) The value of gamma is 1.4. The value of R is 287 J/kg.K Since, the temperature varies with altitude according to the standard atmosphere model, the value of the speed of sound varies with the altitude also.

What is the formula for Mach?

The formula of Mach Number is: M = u/c. Where, The Mach number is M. Based on the limits the local flow velocity is u. The speed of sound in that medium is c. We can say the speed of sound can be equated to Mach 1 speed. Thus, Mach 0.75 will be 75% of the speed of sound that is also called subsonic, and Mach 1.65 will be 65% faster than the speed of light, which is also called supersonic.

What number is Mach?

The Mach number is named after Austrian physicist and philosopher Ernst Mach, and is a designation proposed by aeronautical engineer Jakob Ackeret. As the Mach number is a dimensionless quantity rather than a unit of measure, with Mach, the number comes after the unit; the second Mach number is "Mach 2" instead of "2 Mach" (or Machs).
