Problem $5.$

Air at $2$ bar, $350$ K enters a nozzle operating at steady state with negligible inlet velocity and expands adiabatically to the exit, where the pressure is $1\mathrm{.}4607$ bar. If the isentropic efficiency of the nozzle is $0\mathrm{.}93,$ then determine for the nozzle $($a$)$ the actual temperature at the exit, in K $,$ and $($b$)$ the actual exit velocity in $\backslash (\backslash$mathrm$\{$m$\}/\backslash$mathrm$\{$s$\}\backslash ).$
