Mach Number of Moving Object Formula Elements

Variables

Mach Number

Mach Number is a dimensionless quantity defined as ratio of speed of object to speed on sound.

Symbol: M_r

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Mach Number

Velocity

Velocity is a vector quantity (it has both magnitude and direction) and is the rate of change of the position of an object with respect to time.

Symbol: v

Measurement: SpeedUnit: m/s

Note: Value can be positive or negative.

Formulas to find Velocity

Speed of Sound

The Speed of Sound in air is the distance that sound waves travel through an elastic medium per unit of time, and is denoted by the c symbol.

Symbol: c

Measurement: SpeedUnit: m/s

Note: Value can be positive or negative.
