Formula:`M = V / a`

## 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.
