I have a problem for my Gas Dynamics homework, in which the problem asks to solve for the Mach number at the throat of a converging-diverging nozzle.
I assumed that the Mach at the throat should be equal to 1 since the professor said it was impossible to have a Mach number greater then 1 at the throat.
After showing the same problem to a Graduate Student I work with he showed me that it is possible to have a Mach number greater then 1 at the throat through the area ratios.
But after speaking to my professor a second time he has again said it is not possible.
So my question is.. is it possible to have a Mach number greater than 1 at the throat.
Oh the conditions for the problem are as follows:
Mi=2
Ai=20 cm^2
Athroat=15cm^2
Shock Area=22 cm^2
Ae=25cm^2
where gamma= 1.4
according to the solutions Mach at the throat equals 1.662
I assumed it was 1 but it was not correct.
If someone could steer me in the right direction I'd appreciate it thanks!
