Mach Number

Theory & Logic

Theoretical Background

Physics describes the fundamental mechanism of the universe. The Mach Number is an essential tool for understanding Mach Number in quantitative terms. Calculate M = v / c (speed of sound).

Mathematical Formulation

The relationship between the variables is governed by the following equation:

Result = v ÷ c
Eq 1.1: Governing Formula

Variable Legend

Symbol Parameter Unit
v Object Speed m/s
c Speed of Sound m/s

Practical Calculation Example

Problem

Calculating the result when:

  • Object Speed = 5 m/s
  • Speed of Sound = 35 m/s

Solution

Substituting into Eq 1.1:

Result = 5 ÷ 35
