Introduction

The Mach number can be used to determine if a flow is compressible or incompressible. This page allows you to calculate Mach number for any fluid, just adjust the speed of sound in the fluid to match your requirements!

Calculations

⬇️ Inputs



Velocity (m/s)

⬆️ Outputs



Mach Number
:0.2915


Explanation

The Mach number represents the ratio between velocity and the speed of sound in the surrounding fluid. Mach number can determine whether a flow is compressible or incompressible.
