In the process of spraying liquid from the nozzle, must the pressure at the outlet of the nozzle be equal to the atmospheric pressure?

During my studies, with high Mach compressible fluids, I always set the outlet pressure to 1 atm. In that case I can roughly calculate the exit velocity. However, in the case of steady flow, is the outlet pressure still equal to 1 atmosphere? As shown in the picture: Thank you very much

Are you sure the ambient pressure at the outlet will always be 1atm? – Solar Mike Nov 30 '22 at 06:30
@SolarMike I am not sure. – yuxuan Nov 30 '22 at 10:56

It is if your dischrge is at sea level at STP. – Tiger Guy Dec 01 '22 at 06:07
