$6-16.$ A gas with a flow rate of $300mo\frac{l}{m}in$ enters a steady$-$state, adiabatic nozzle with negligible velocity at $T=500K$ and $P=\frac{10}{b}ar$ and leaves the nozzle at $P=\frac{1}{b}ar.$ The gas has $C_P^{**}=40\frac{J}{m}ol*K.$

A$.$ Find the exiting temperature and exiting velocity if the gas is ideal and the nozzle is reversible.

B$.$ Find the exiting temperature and exiting velocity if the gas follows the equation of state above and the nozzle is reversible.

C$.$ The gas follows the equation of state above, but the nozzle is not reversible; it has a rate of entropy generation of $S_{\text{g}\text{e}\text{n}}^{}=1\mathrm{.}5k\frac{J}{m}in.$ Find the exiting temperature and exiting velocity.
