How to Calculate the Mach Number of Flow at Nozzle Exit

In order to calculate the Mach Number of the flow at nozzle exit we require the temperature at the nozzle exit which is denoted by Te in Kelvin (K).

 

 

Furthermore, we also require the velocity of the flow in the nozzle exit denoted by Ve.

 

Since, speed of sound in the nozzle at exit is given by

Speed of sound = ae = square root (gamma*R*Te)

 

where, Te is the temperature at nozzle exit,

R is specific gas constant = 287 J/kg.K

gamma for air  = 1.4

 

So, the Mach Number of the flow at the Nozzle Exit is then,

 

Mach Number , Me = Ve/ae

Mach Number is a non-dimensional quantity and so it has no units.
