Hi
Just a quick question about Conservation of Mass that I somehow managed to confuse myself:
If I have a vent of constant cross section at steady state, given that conservation of mass means that inlet and exit mass flow rate must be the same, does this mean that, taking the compressibility of gas into account (for this example I'm assuming Ma > 0.3 although unrealistic in real life), this means that the exit velocity must be greater than the inlet velocity (temperature and pressure are the same in inlet and exit)?
Basically my question is (and I know this sounds stupid), conservation of mass holds always even if the gas is compressible?
Thanks
