We need a pristine table or diagram. Please deliver a perfect solution quickly. AN$10"$In a gas turbine, the mass flow of air into the turbine is $4\mathrm{.}00$ kg$/$s and the air has a pressure of $12\mathrm{.}0$ bar and a temperature of $900$C$.$ The air expands and the pressure is lowered adiabatically to $1\mathrm{.}00$ bar. The turbine's efficiency is $87\%.$ Calculate the temperature of the air flow out of the turbine. Specific heat capacity of air is $=1\mathrm{.}005$ kJ$/$kg K and $=/=1\mathrm{.}40.$

$($Answer: $-2\mathrm{.}08$ MW$,655$ K$)"$
