Problem $08\mathrm{.}073-$ Air entering and leaving an adiabatic nozzle

Air at $500$ kPa and $400$ K enters an adiabatic nozzle at a velocity of $\backslash (45\mathrm{.}00\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash )$ and leaves at $300$ kPa and $350$ K $.$ Use variable specific heats.

Problem $08\mathrm{.}073.$a $-$ Exit velocity of air

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

The exit velocity is $\backslash (\backslash$mathrm$\{$m$\}/\backslash$mathrm$\{$s$\}\backslash ).$ Problem $08\mathrm{.}073.$b $-$ Isentropic efficiency

Determine the isentropic efficiency.

The isentropic efficiency is Problem $08\mathrm{.}073.$c $-$ Entropy generation

Determine the entropy generation. $($Round the final answer to four decimal places.$)$

The entropy generation is $\backslash (\backslash$mathrm$\{$kJ$\}/\backslash$mathrm$\{$kg$\}\backslash$cdot $\backslash$mathrm$\{$K$\}\backslash ).$
