A convergent$-$divergent nozzle with $A_{ds}=1000m{m}^2$ and $A_c=3000m{m}^2$ operates

under a stagnation condition of $200$ kPa and $45C.$ If a normal shock is present in

the nozzle at a location with area $2000m{m}^2,$ determine the exit pressure and the

pressure loss experienced by the nozzle flow.
