Mach Number Calculation

Introduction to Mach Number Calculation

The Mach number represents the aircraft's speed as a multiple of the speed of sound. In fluid dynamics, it is a dimensionless quantity that can be calculated by dividing the velocity of the object by the local speed of sound. In this formula, M represents the Mach number, V is the velocity of the aircraft, and a is the speed of sound in the medium.

Parameter usage:

• V = velocity of the object
• a = local speed of sound

Output:

• M = Mach number

Data validation

The velocity and speed of sound should be greater than zero.

Summary

This formula helps in calculating the Mach number, which is crucial in aerospace engineering and fluid mechanics.
