What is the design Mach number? If you know the exit Mach number then you can easily compute static pressure at the exit.

yeah very thank you sir,
i have calculated by using pressure ratio and mach number(M=2) relation.
now i have pressure ratio about 7 of nozzle.
for this problem what turbulence model should i use k-e or spa.alm?
and why?

You should run both so you can develop experience in determining which one gives better results in these sorts of flows.
