Problem $08\mathrm{.}035-$ Hot combustion gases in the nozzle of a turbojet engine

Hot combustion gases enter the nozzle of a turbojet engine at $\backslash (260\backslash$mathrm$\{$kPa$\},747^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ),$ and $\backslash (80\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ),$ and they exit at a pressure of $85$ kPa $.$ Assume an isentropic efficiency of $\backslash (\backslash$eta N$=93\mathrm{.}0\backslash )$ percent and treat the combustion gases as air.

Problem $08\mathrm{.}035.$b $-$ Exit temperature of air

Determine the exit temperature. Use the table containing the ideal gas properties of air.

The exit temperature is IK$.$
